I disagree... Many scientific studies have shown that brain patterns in hetero vs. homosexual people are different... leading scientists to believe it's not a "choice".
There shouldn't be any reason to HAVE to legitimize it... Once again, the Christian right brings up an issue that shouldn't be, and then gets mad when someone tells them it's stupid to bring it up in the first place.
I haven't seen any scientific proof that homosexuality is genetic.
We are talking about abnormal behavior. I suspect that's why many people, not just "the Christian right," have a problem with using the government to legitimize this lifestyle choice. If "the Christian right" were the only ones opposed to this, we wouldn't see the overwhelming rejection by voters at the polls.
Keep in mind that people include bisexuals, transsexuals, and transvestites under this umbrella. Do you think those lifestyle choices are genetic too?
