Homosexuality is nothing more than gross self indulgence. Period. Moreover, homosexuals are no more a class of people than are fans of a particular football team. They are not a race. They are people who have chosen, for whatever reason, to have sex with someone of their own gender. Such choices do not a warrant for "civil rights" make any more than someone's chosen preference for a certain team qualifies them for special consideration.
There's nothing remotely bigoted in that, unless it is the bigotry attendant with some of those who disagree, who think homosexuality IS some sort of warrant for special consideration by society beyond that which their deviant, self-indulgent behavior deserves.
