Well, yes, that's usually the case if they answer at all, but it's just not going to cut it anymore because everyone knows that's not the case, even the people using that very argument know that they aren't women in any meaningful way.
So, just once, I'd like a proper explanation of what the difference is, bearing in mind transwomen are just as (probably even more, according to some stats) likely to be sex offenders as other men.
It's very frustrating that they'll call us meanies and bigots, but never just answer the damn question.
