"Now I know you're just PC police, and that I have nothing to gain by further engaging with you."
That's not PC police. This is How To Win Friends And Influence People stuff, not PC stuff.
You are free to be rude, but you'll pay the consequences, quite needlessly.
I'm in a position where I with some frequency have to contradict people (being a code reviewer for a significant internal shared library has that result), but I try to make it clear in my words and tone that it's in the spirit of working with them and obtaining the best solution. I'm pretty sure it's not 100% successful, because some people to some extent can't process being contradicted in any way as anything less than hostility (and I put both "somes" in that sentence on purpose), no matter how polite you are about it, and on my side, I'm absolutely sure I'm not perfect about it, but I am sure I'm better off than I would be if I was always being as blunt as possible without even trying.
