why does the left like to talk dirty?

So the latest is Samantha Bee of  TBS's 'Full Frontal,' who came up with the dirtiest thing you can call a woman to describe Ivanka Trump.

It seems characteristic of people on the left that they use profanity more than people on the right. Certainly rightists feel just as strongly about things as leftists, yet it's overwhelmingly people on the left who use profanity publicly in asserting their views. Why is this?

I think there are a couple reasons for this:

1. One is that that don't know any better. I think this is true of Bill Maher, for example. His use of profanity is just so casual, so unthinking, that I just think that's the way he grew up. Everybody in his family talked that way, all his friends and neighbors talked that way, so to him it was just the way 'everybody' talked. I think this was-- perhaps is-- characteristic of ethnic working-class people and blacks. Somewhere along the line Maher must have learned that most people don't think you should talk this way in public, but by that time he had learned the second reason why people on the left talk dirty:

2. They do it for effect. They think it makes them seem clever. This is particularly true of show-business leftists like Steven Colbert and now Samantha Bee. At one time they may have been right. I think that time has now passed.

3. Democrat party chair Tom Perez uses profanity at public meetings. With somebody like him, I think the reason for this is the one that's customarily ascribed to it: that he lacks the intelligence to articulate specifically what it is that's bothering him, so he resorts to profanity because it's the only, but inarticulate, way for him to express his frustration.
