Many of us DON'T care if that happens. Haven't you caught on to that yet? Many of us would CHEER if they got that right. Indeed, who SHOULD be getting their panties in a bunch over OTHER PEOPLE'S relationships? No one, that's who.Wastey
Honestly, why do u, or any other SSMers care if polygamy or incest is legalized?
But you haven't been asking WHETHER those relationships should be legalized (at least not that I've seen). You've been asking why they shouldn't be immediately legalized WITH same-sex marriage. That's a different question.
For THAT question, we've been giving you answers. Answers like: Because they're separate issues. Because they have unique obstacles that need to be addressed first. Because they make changes to the finer points of marriage law, which same-sex marriages do not. Because there is no national push to address the matters, not on the scale of gay rights. Because they have well-documented histories of (patriarchal) abuse. Because people aren't born with the propensities to ONLY love multiple people at a time, or to ONLY love relatives.
Some of these reasons may be adapted, or directly applied, to arguments against polygamy and incest. But they all recognize the need to view these issues individually, taking separate steps to address their separate aspects.
This doesn't mean we care that polygamy and incest not be legalized. It means we care enough to be methodical, thorough and fair about all these issues, rather than suggest they all be crammed into a legal blender, in hopes that one solution pours out for all of them.
