If homosexuals were required to state on their health insurance forms their sexual preference, do you think they would be able to afford the premiums that actuaries would set for them, given all the health problems that come part and parcel with homosexuality?

Obviously homosexual activity opposes the common good or the common welfare. Well, it used to be obvious, anyway.

Yeah. BTW, for any social conservatives lurking this thread, the socialization argument is an extremely fruitful one. There's no answer the "if I'm not hurting anyone, it's my business" crowd can give to it, because no act happens in isolation.
