The difference between Homosexuality and Polygamy is that Polygamy is a behavioral choice. Some religious folks disagree, but everyone knows they can not control what makes their soldier salute.
What should this have to do with any religious "norm?" Homosexuals are not looking to change others religious beliefs; they simply want to be treated equally.
Lawmakers should think about homosexual teens. Gay teens already commit suicide b/c they are ostracized by parents and peers. Telling them that they can not legally be accepted as adults will surely cause greater depression and possibly increase hate crimes.
It wasn't long ago that interracial marriage was illegal.
Frode-at least you are asking questions. That's more than most politicians will do.
