You are entitled to your opinion. I think sexuality is a pretty good basis for determining the importance of sex, and white knightery is admirable.
It isn't really "female innocence" that is significant here, though. It's youthful female sexuality. It seems, and I confess that this time I really am trying to "read minds" i.e. infer a position from a partial statement, that the "innocence" aspect must come from the oft repeated, but always wrong, error that the problem is that the young ladies would be scandalized, offended, or perhaps even frightened by the sight of a nude male. I'm not sure where that idea comes from, but people say it all the time, and that's what I think you are referring to.
In reality, the problem is not what they might see, but what might be seen, and by whom. In an anecdote I repeat often, because it illustrates the problem so well, the school board member assured some complaining young women who were requesting a transgirl not be allowed to use the girls' locker room that the transgirl would always wear a towel so that his male member would not be seen, to which the young woman replied, "Can she wear it over her eyes?"
Perhaps that wasn't your thought regarding "innocence". I may have mistakenly believed that your thought was the one shared by the school board member above, and expressed so frequently on these threads.
Ah well. It's all well worn territory. It comes back to things said on this thread and all of its predecessors. Either sex matters, or it doesn't. If it doesn't, then it doesn't matter for anyone, in which case no one ought to care if they are called a man or a woman. If it does, then we ought to define the terms. However, the situation we find ourselves in is that there are large numbers of people insisting that while no one really ought to care who gets called what, there is a small group of people for whom it is very important to be called one or the other, but the terms that are actually in use are undefined.
And just to recap my original contribution that reignited my participation in the thread, it was said that it was courteous to refer to people in the manner in which they wish to be referred. However, I have to question the courtesy of anyone who insists on being referred to as one sort of thing, when they acknowledge that they are not that sort of thing, nor will they even attempt to appear to be that sort of thing. That practice ends up making the reference meaningless.
