"Tolerance is widely accepted as an admirable virtue, but it still feels cheap to me. Essentially what Palin is saying is that she puts up with homosexual couples. There's no approval there, no acceptance, just respectful disregard. The difference between "tolerance" and "acceptance" is like the difference between looking the other way and actively supporting something."
Oh, WAAAAAH! Sorry, but some people just aren't going to fully support gay marriage, and you're crazy to expect them to. Why should they? Tolerance is the best you're going to get, you live your life and I'll live mine. I don't ask you to "fully support" MY lifestyle, mostly because I don't need you to. Nor would I expect the pro-choice crowd to "fully support' my pro-life stance, although I expect them to "tolerate" it, just as they ask me to "tolerate" a woman's right to choose. And I'm sure gay couples who live in states where gay marriage has been banned would dearly love some of that "tolerance" you are so down on. I have a respectful disregard for gay marriage - if gays want to get married, fine by me. Just don't expect me to pat you on the back for it.
