My opinion is that we (gay and striaght people) are indeed equal from a human standpoint. We should all have the same rights, opportunities, etc. We cannot live in a world rife with this sort of prejudice when a person can get fired from a job because he's gay regardless of his qualifications.
On the other hand, our relationships simply aren't equal...gay marriages v straight marriages. You can change the word all you want..change the meaning, but it doesn't alter pure facts.
Its my opinion, and yours to see otherwise, that since homosexuals can't bear children on their own which is a necessary function of human survival, how can their relationships be equal?
On the surface, hetero relationships do add more value to society -- they provide future scientists, engineers, etc. Gays depend on heterosexuals for adoptions, and other people outside of their own mate (gay or straight) to lend their biological material whether it be through surrogacy or sperm donation, to legally have their own families.
So while we're all equals, our relationships simply cannot be.
