I never talked about girl's beauty. Idk why you're totally Changing the topic. A beautiful girl isn't the problem here, you literally suported girls going topless. That is the problem don't divert from the subject.
If it needs to be said, no I'm not in favor of women going around topless in my town and country; heck I'm not even in favor of bikinis. I just am not going to immediately condemn people out in the middle of nowhere Africa or the Amazon basin where it's normal and perfectly acceptable dress for all the women to go around topless (though I'm not sure that even if I lived long term in one of those places I'd adapt and do the same myself while there).
But it is a problem when people start to think that men's lust or inappropriate sexual behavior (as distinguished from momentary, involuntary arousal) is excused by or an unavoidable outcome of what a woman wears or looks like or does. And I don't even think you're someone who is trying to excuse or justify such; you're just using arguments that logically lead to such a conclusion. Yes some women make it harder for men to maintain pure thoughts, and that's not a good thing. But it also doesn't automatically mean that all women who wear clothes that show more skin that you are comfortable with are sinful and godless.
