The gay's biggest fear is finding out there is a cause for what they do, and a way to explain it.
Or even worse, cure it.
I think that the cause is environmental...either a lack of proper parenting, or some form of sexual abuse when they are very young and unable to even remember the abuse...
and then, in some cases, it comes as they enter adolescence, go through normal fears of rejection by the other gender, and are approached by a homosexual who convinces them to try playing the other team...
and once they have played the game, it then becomes self-fulfilling because, like an alcoholic who knows they should not take another drink, they feel compelled to do it anyway...
once they have reached a certain point, I think it is virtually impossible to correct the problem. Like an alcoholic, they are compulsive and the only thing they could possibly do is abstain...
Or, we can just pretend they are normal, allow them to marry, teach young children that it is homophobic to refuse a date or approach from a homosexual, and see the numbers grow. (OK, that last line was sarcastic)
