I personally don't think he is homosexual, he didn't say it, someone claims he said it. And if you look at the question, maybe he didn't like the girls in his highschool, that doesn't necessarily mean he doesn't like ANY girls.
I think the guy is very bright, but immature and confused and someone just saw an opportunity to throw in the homosexuality angle for their propaganda purposes.
Actually, he sounds interesting. If he pulled something like this in the US he would be famous by now.
