That was an interesting discussion. The only thing I would question about it is that it grants the assumption that being homosexual is equivalent to being black or Jewish and that, therefore, anti-discrimination laws should be applied in precisely the same way. However, if this assumption is incorrect, if homosexuality is about behavior rather than something genetically innate, then homosexuals should not necessarily enjoy the same rights as those other categories of people, at least not if one seeks to base them on the concept that homosexuality is the same kind of thing as race. It is certainly a debate worth having. Although it seems that the aforementioned assumption has essentially been codified by Supreme Court decisions here in the U.S., that doesn't necessarily make it right.
