Idk, I haven't studied it extensively but, if you look in the Bible, you can see where homosexuality is mentioned. This tells me that the practice of homosexuality has always been happening. I'm willing to bet that, if you look in all the "good books", there will be some mention of homosexuality (along with guidance)
It just seems to me that, if all of these books mention homosexuality, them homosexuality has always been around. That makes it a normal part of life, regardless of how much anyone fears it. Since it's always been around, it's not a feminine designed attempt to "suppress" anything in men. Definitely not a recently manufactured covert movement.
Is tranny time at the library a good idea? I'd take my kids, if only to help them understand what it is, and to teach them acceptance and not to hate. The good news is that, we parents have a choice.
