What's to misinterpret? His point is right there:
ppl should use the bathroom of which gender they want to identify with
Nothing to do with "blokes putting on frocks to use the ladies". The point I disagree with is right there, I don't want any old bloke moseying into the ladies when my wife and daughter are in there and being able to weasel his way out of it by simply claiming he "identifies as a woman". **** that.
Again, if that makes me an idiot or a bigot then I'll happily be one.
