When you say something you know is politically incorrect, do you take pride in knowing you are upsetting some people?

I hear people saying “This might be politically incorrect” who then go on to state something that is hurtful to others. Why state something that might hurt others, in a way that you know will hurt others.

Is it because the speakers lack language to describe something in non-hurtful terms? Is it because the speaker enjoys hurting others? Is it because the speaker takes some pride in acting in a way contemporary people with manners have chosen to act?

Is that it? Some impulse to exhibit a lack of manners?
