ETA-oops forgot my main point to the "states right" camp:
Y'all should read your handy dandy constitution more!
"No state shall deny to any person within its jurisdiction the equal protection of the laws."
States cannot defy the constitution. EVER. PERIOD.
And the Supreme Court has identified marriage as a constitutional right FOURTEEN TIMES.
DOMA--unconstitutional--remember?
Sure glad abortion wasn't a state issue.
It's not a "States issue" (as Jeb! Or Bobby Jindal might like you to believe).
There are 138 Federal (federal alone!) rights gained through legal marriage.
Social Security Benefits, tax benefits, COBRA, estate planning, military benefits, medical benefits, family benefits, housing benefits, consumer benefits, plus other legal benefits & protection.
For the religious objectors? Don't do it.
I've never personally known anyone who wanted to marry their pet (although the implied reference to bestiality is truly disgusting to me) but I've known many gay people who've been living together for decades that can now legally decide things like medical care for their spouse.
Oh--I'm sure there were a WHOLE lot of people that objected to the abolishment of slavery too? Guess what? No O. cared what they thought either when the country, instead, decided to move FORWARD!
