If homosexuals don't want to be like heterosexuals, which seems obvious enough to me, then why do they want to do a heterosexual thing like get married? If they were truly committed to their caused they'd adopt a different term, like "homounionization" or "homobonding."
Statements like this is why people keep labeling you a bigot. It's natural to want to couple with someone who you are sexually attracted to. Homosexuals, since by definition are attracted to someone of the same sex, will then want to naturally couple with someone of the same sex. It's not that they don't want to be like heterosexuals, it's that they want the right to marry the person they are coupling with, just like heterosexuals. If you honestly can't understand this then you have no compassion for you fellow human.
