They don't just make dumb points and give the left ammo though, they make insidious points that derail the positions we should hold. It does matter how people we share a society with "identify".

It matters if anyone (supporters or opponents) talks about trans freaks on girls sports teams like it's everyday politics and not one tiny aspect of an enormous, conscious effort to subvert and destroy sane, rational society.
