We need blessings not curses.

   Typically in political discourse we expect our political leadership to express proper etiquette. Implicitly entailed in that is banning the use of profanity. 8 yrs ago Donald trump shocked the world with profanity in his campaign speeches. Now both the democrats and republicans have come around to "let it all hang out".  The politicians can be their natural selves. [nasty and foul]
during the presidential debate Joe Biden swore at least half a dozen times. The GOP convention also had several occasions' from not one, but many politicians cussing.
  Some secularist will emphasize the benefits of cussing such as authenticity, a release of frustration etc. But the benefits are outweighed in the end. As they come off rude and unsophisticated. 
   Typically you here about hard laborers developing cussing habits because of the burdens they bear. Not something you want seen coming from the privileged. But more than this profanity is a social ill that does drag lower elements of society with it,  Even secular studies can sometimes notice this*  People are unhappy with the wrong worldviews and faiths.  They grow bitter in their unsatisfaction with life. They develop the profanity habit.  They get stressed out and turn to depressant drugs.  They end up 
      These habits find themselves knitted into the fabric of other secular problem eroding society.  The cumulative effect builds on to crime evils and calamities. of course profanity in private is a minor problem but profanity in the public square pollutes the attitude and magnifies in a  chain reaction.  People start having fits of violence and misbehavior, they progress towards drugs and then the criminal element after being ostracized,  When public officials engage in these tactics they incubate an environment that contradicts their mission.
     In the previous generation, a point of libertarian ethics towards foul language gave way to social anarchy.
     It appears that socialists have had creative response by deconstructing and reconstructing profanity into what we have seen as the social justice movement.  Dirty language is sill encouraged but the new profanity is focused on race, sex and religion. by encouraging these pour habits society, dare we say the hegemony is deconstructed,  Thus giving way to the coming tyranny (if not the current tyranny).  As the language leads to behavior control.
 God is a loving God that encourages his people to use their mouths to bless instead of to curse.  Jesus wants us to promote peace instead of instigating violence.  Instead of deconstructing society we should be reconstructing the family and society.  Promoting the Holy over the profane  keeps us with a self controlled focus and demeaner if politicians want to promote freedom they should promote responsibility.  In peter's darkest hour he cursed. In his greatest our he blessed.

Mark 14:70 And he denied it again. And a little after, they that stood by said again to Peter, Surely thou art one of them: for thou art a Galilaean, and thy speech agreeth thereto.71 But he began to curse and to swear, saying, I know not this man of whom ye speak.72 And the second time the cock crew. And Peter called to mind the word that Jesus said unto him, Before the cock crow twice, thou shalt deny me thrice. And when he thought thereon, he wept."
acts 10:34 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons.  35 But in every nation he that feareth him, and worketh righteousness, is accepted with him."

James 3:5 Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!6 And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.7 For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind:8 But the tongue can no man tame; it is an unruly evil, full of deadly poison.9 Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.10 Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be."
Proverbs 3:15 A soft answer turneth away wrath: but grievous words stir up anger."

Romans 3:12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.13 Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:14 Whose mouth is full of cursing and bitterness:"

Swearing, or uttering a word that is considered taboo, is an often-ignored part of our language due to the controversial nature of the topic and the potential negative consequences of swearing. In 1901, Patrick [2] concluded that swearwords are primarily used by soldiers, sailors, laborers, uneducated people, and criminals, and men make up the majority of these social groups. While swearing has been considered a predominately masculine activity, women now tend to swear as much, or even more often, then men [3]. Since swearing is considered taboo, these words are usually judged as shocking, and the swearer may be considered antisocial and offensive. Consequently, swearing can negatively impact how the swearer is perceived by others, which may lead to social isolation and depression. In groups of women with rheumatoid arthritis or breast cancer, Robbins et al. [4] found that swearing was related to increases in depressive symptoms, and this association remained significant even after accounting for variances in the depressive symptoms associated with disease severity. Interestingly, only swearing in the presence of others, and not swearing alone was correlated with increased depressive symptoms [4]. In specific contexts, swearing has been shown to produce negative outcomes."

"Recent research has shown that this emotional impact can have an analgesic effect, and there's other evidence that strategically deployed swear words can make a speech more memorable. But it's not all positive. A new study suggests that swear words have a dark side. Megan Robbins and her team recorded snippets of speech from middle-aged women with rheumatoid arthritis, and others with breast cancer, and found those who swore more in the company of other people also experienced increased depression and a perceived loss of social support."

"Brad Bushman, a media expert at Ohio State University who was not involved with the study, concurs after reviewing the research.
“This research shows that profanity is not harmless,” said Bushman, a mass communications professor. “Children exposed to profanity in the media think that such language is ‘normal,’ which may reduce their inhibitions about using profanity themselves. And children who use profanity are more likely to aggress against others. These are very important findings for parents, teachers, and pediatricians.”
"The connection between profanity and adolescent aggression remained significant even while accounting for the influence of portrayals of aggression in the shows and games popular with the middle school students involved in the study.
