I agree with you largely. I was never abused or groomed and if I think back to some earliest memories, I can remember particular behaviour traits that you would probably look at and regard as feminine or camp. Yes my dad was an arsehole, but he was to all three of us and my brother who is five years older is straight. I definitely don't have a fixed theory where it comes from, but yes of course it is fundamentally unnatural, because it's an exception to a norm. Why 99% of gays refuse to tolerate that fact is alien to my mindset and logical thinking.
