Pram, I know this is probably way beyond your comprehension, but try to conceive that maybe other people have an interaction with gay people that's different than yours. You seem to have this filter over your glasses that only allows you to see gays who are child molesters and cross dressing parade marchers.
You know, typically conservatives espouse the value of seeing everyone as an individual and weighing their character based on individual merit. Most of us (though not you obviously) don't make an exception to that rule, suddenly becoming collectivists only so as to denigrate gays.
