Yanno.................you can't be indoctrinated into being gay. Either you are or you aren't.
And.................I don't think that reading a story to a child is going to turn them to the gay agenda. At most, it might open their mind enough so that when they become adults, they can at least be tolerant of others.
You don't know that. Children are most often raised with the idea that they will marry the opposite sex one day and have their own children. That course being set, it almost always turns out that way. But when kids are told that marrying another boy and having gay butt sex and then adopting an innocent child to complete the illusion of "family" is just as normal as a real family with a mother and father, they're going to be set upon a different vector of thought and sexual development. Right now homosexuals represent about 2-3% of the population, but historically have been the majority in many civilizations that were subsequently brought asunder by it. So yes, homosexuality can be groomed, taught, and prosyletized until it becomes the rule and not the exception.
Actually, it's not been that way in my experience. When I was in 3rd grade, I had a sleepover at a friends house and during the course of the evening, one of them asked me if I would be interested in having gay sex. I said no, packed up my sleeping bag and went home right after that, because it sounded wrong to me.
I've known since I was 7 that I was straight.
A few years back, I was friends with a gay female, and we spent a lot of time hanging out and shooting pool. After I'd known her for about 6 months or so, she asked me one day if I would help her out. I told her sure, because she was a friend and asked what the favor was. She stated that she'd never had sex with a male, and she wanted to see if she really was gay or not. Well............we started to have sex, but then she stated that she didn't feel right and wanted to quit.
No.....................gay is not a choice.
