Kristin, you know the really funny thing about all this is that if gay people conducted themselves with consideration for those who differ from them (exactly what they're asking for, but apparently not wiling to return), you'd probably see even more than the 57% or so percent of Americans (not all, as you imply) going "fine, whatever!"
If those two gay men had NOT sued the florist I happen to know, and if the vitriol toward her (a loving woman) from the left had not occurred, prompting our State Attorney General to unleash the full power of the State against her, as of today I'd be disappointed in the Supreme Court for its disregard for the basic tenets of federalism, but would not even have commented on this thread.
In my state, around half the voters were still uncomfortable with gay marriage, and the ink was barely dry on the law when the florist's treatment by these men hit the news. In talking with people about this, I've found that most thought that gays would get to marry, fine, and they'd respect the freedom of others to participate, support, or be involved in such marriages OR NOT. That's what I expected. But we were all wrong.
