Profanity paradox

Profanity is simply blasphemous or obscene language that is offensive or disrespectful. 

• As children we’re taught that cursing, even when we’re in pain, is inappropriate, betrays a limited vocabulary or is somehow low class. But profanity serves a physiological, emotional and social purpose and it is effective only because it is inappropriate.
• Profanity is a cultural construct that perpetuates itself through time.
• Profane words have a direct line to our emotions. They are a spontaneous reflection of strong emotional states, like anger, fear or passion. They are also unequaled in their capacity to inflict emotional pain and incite violent disagreement. 
• Swearing and cursing are often used interchangeably, but there’s a subtle difference in their origins. A curse implies damning or punishing someone, while a swear word suggests blasphemy. Both words are defined as profanity: vulgar, socially unacceptable language not used in polite conversation.
• Profane words that provoke the most repressive regulatory reactions from the state in the form of censorship and legislation. Bad words are powerful -- emotionally, physiologically, psychologically and socially. The paradox is that profane words are powerful because we make them powerful. 
• Profanity is learned differently. It’s articulated differently. It changes differently over time. Every generation has its own slang, including profanity.
• Cable television and the Internet have created a wild west for words, where the true will of the people has its way. And if social media are any indication, the people want to be able to swear. And to hear swearing. And to read swearing. As the public has become more accustomed to profanity, taboo words have started to make their way more prominently into mainstream science.
• To capitalize on profanity to learn about language, not just as the rational product of deliberate reflection, but as part of the impulsive, emotional, hot cognition that is pervasively human. Cursing is coping, or venting, and it helps deal with stress. Profanity was associated with less lying and deception at the individual level. People who use profanity are more honest. Liars have to use more brain power, require more thinking, remember lies to avoid telling the truth. Truth tellers, on the other hand, get to the point faster, which might mean speaking impulsively and without a filter.
• When profanity targets demographic groups, it can foster prejudices. These words don’t have any intrinsic, mystical power that confers superhuman strength and endurance. It is simply the act of speaking a taboo word that makes it cathartic.

The foolish and wicked practice of profane cursing and swearing is a vice 

so mean and low that every person of sense and character 

detests and despises it ... George Washington

Profanity generally indicates the weakness of the person and lack of vocabulary skills. Whatever is said in conjunction with profanity gets lost in the noise and people of character will distance themselves. When profane words are used in forums, the person will get castigated and compelled to withdraw those words and apologize unconditionally. If you want people to think that you are telling the truth, then swearing might be helpful. Profanity is unnecessary and should be censored. If the foul-mouthed among us want to preserve the benefits of cursing, we need these detractors to ensure that profanity stays profane.
