So basically what you're saying is that the racism analogy I used is invalid because your entire marriage argument stems from procreation? That's what you mean by "not scientific", right? That marriage between two men or two women shouldn't be legally recognized because they can't procreate? Well, then I guess in order to remain logically consistent, you're against casual sex between a man and a woman, condoms, birth control, and oral sex and anal sex, too, right? How bout the fact that two homosexual people can procreate? Surrogate mothers, in vitro fertilization, there you go
Regardless, the 14th amendment guarantees all citizens equal protection under the law, marriage is a legal institution, therefore, the 14th amendment guarantees homosexual couples the equal protection under the law to enter into the union of marriage. The Supreme Court will decide on that this month and I have a feeling they're going to say something similar
Like I tell everybody against this sort of stuff, you're on the losing side of the fight, equal rights is an inevitability. It's going to happen.
There's nothing you can do to stop it, so bring a raincoat
