Are their different levels of political correctness? For instance, someone who uses the word "bitch" but doesn't use racial slurs? Bitch is considered a sexist epithet so one might argue that you're not considered PC if you use it. 

Is it possible to be politically incorrect while sharing and fighting for liberal ideas, equality, BLM, LGBTQ rights, feminism etc? 

What do you associate political correctness with, specifically and why? 

I personally believe there are different levels of everything, including political correctness. I'm a liberal and I consider myself politically incorrect because I don't walk on egg shells around people and give words more power than they deserve. I don't use racial slurs, I don't use words that I believe are hate speech. I fight and donate to liberal causes. But when I describe myself as politically incorrect, I'm automatically associated with bigotry or Donald trump.
