@Brainbug: Probably worth noting it's nicely on the bad argument side since, near as I'm aware, what we've been able to parse about homosexuality on that front is that it's a pretty likely to be a feature, not a bug. It's a fair bit of a guess, in practice (as just about everything conjecturing about evolutionary history), but the argument that having a subset of non-reproducing members that still are otherwise functional is beneficial to a gene pool isn't a difficult one to sell by any means, and that's not exactly the only argument in favor, there.
... but yeah, generally, while there may have been good arguments against in the past (sorta', barely -- mostly related to disease, potential physical complications of the acts involved all still applicable to hetero relationships, mind, if with different degrees of incidence, and reproduction which was always a poor one, considering homosexuals aren't sterile, just uninterested), conditions today aren't conditions of the past save in very few locations where you seriously have bigger problems, and the concerns those arguments attempted to address are non-concerns at this point, if attended appropriately. Medical knowledge and material/chemical science beat the specter of Sodom below the point it mattered years ago.
E: And now take a moment of contemplation to anthropomorphize those, put them in lucha masks, and set them loose in a ring.
