I dunno about you, but I wouldn't want to RP with someone who didn't believe in evolution, point blank. I could tolerate them believing that it doesn't exist in Hydaelyn/exists in Hydaelyn in a fashion that is distinct from how it works in the real world, but if they don't believe in it in general, it's a rock-solid sticking point for me. It's all well and good to say "everyone's headcanon is valid", but that's a thing that goes beyond headcanon.
