When they complain about people being 'PC', what they really mean is that folks are calling them out on their homophobia, transphobia, sexism and racism.

Because I have heard ZERO policy positions out of any voters who seem to have made this their "single issue" agenda. And so I'm trying to figure out how deep the actual legislative rabbit hole goes with these people, and it's a mystery.

in public at all times.

What do they expect them to do?

And the more blatant and intemperate the language used, the better.

I don't know if it's about concrete policy, so much as sheer attitude.

Which ironically, taken to its logical conclusion, would violate the free-speech rights of those who disagree.

it is very convenient if people can be made to avoid pointing out your racism, homophobia, nativism, misogyny, etc. Denigrating 'political correctness' allows them to appeal to these sentiments without fear of being called out for it. It would play into the hands of most republican politicians.

Where else can it go?

Anger, revenge, fear, hatred -- these are what conservative messages play on. If PC means that you take out the name calling, and the loaded language then they don't like it. That is ALL they want to focus on -- their own anger, fear and hatred.

For example if you say "global warming is a fact" their brain goes "I hate smarty-pants liberals" and then stops. It never makes it to the 'what is the evidence for or against global warming' part.
