> Another argument I've seen and that I've never seen addressed is: why do gay couples get to marry and not polyamorous people? Seems like there is a double standard here.
Restricting marriage to pairs of opposite sex plainly discriminates on sex in the same way that restricting marriage to pairs of the same race discriminated on race. Who you are permitted to marry is determined by your race/sex.
Limiting marriage to pairs does not discriminate in the same way. It may or may not be an inappropriate restriction, but its not the same type of discrimination that is at issue with either the opposite-sex or the same-race restrictions, so there is no "double-standard" in eliminating either or both of those restrictions and not eliminating the restriction to pairs.
