I've not read all of the posts here, so forgive me if I'm repeating something that has already been said.
Hubbard had a very big issue with gays, and as a result the cult that he created has very big issues with them. The followers of the cult hate gays without even being told to, it is steeped in the group-think of the cult. The culties can't tell you WHY they hate gay people, because they don't know themselves. They can come up with rationalizations as to why, but those should not be confused with a reason.
Hubbard probably went over the deep end when it came to gays when it turned out that one of his sons was gay. Of course the inability of his vaunted "tech" to cure gay people of their desire to smoke sausage and take it up the tail pipe didn't do anything to improve his opinion of them I'm sure.
Gay people have got bad wiring. Its like being dyslexic. Something in their brain is different. Some people will try to tell you that it is a choice, but then why would anyone CHOOSE to be a leper? Whatever it is, it is something that they are either born with, or that happens to them very very early on in life.
But whatever it is that makes them the way they are, it isn't a reason to hate them. I will say that the promiscuous behavior of the vast majority of male homosexuals does upset me. That kind of thing is how and why AIDS became such a plague for them, and continues to be so to this very day. If they would choose monogamy over promiscuity, and practice safe sex, then AIDS would cease to be a problem in short order. But that isn't going to happen because while they may be gay, they are also men. Women are the ones who act as a moderating influence in heterosexual relationships. When the scene is boys without girls, the result is a fuck fest without end with more STD's than you can shake a stick at.
