I've had five (now over 10) or more conversations with heterosexual (all women) friends about prop 8. And they all tell me how angry it gets them. "It's a civil right." (Meaning not up for debate at all.) They are all married or have been married or are about to get married and are so happy for my partner and I being able to get married and they are all taking the yes on 8 stuff very personally. I am so deeply touched by their passion. It's funny how you get when your relationship and orientation are not taken seriously. You get used to the institutional discrimination as fact and feel privileged to finally be allowed to get married.
And I must admit to having Eeyore moments some times in the "Oh, they're going to take it away again. Oh well." Even though I would be profoundly disappointed if 8 passed, as it means a lengthy delay while we wait for the demographics to continue shifting in our favor as they already are, so the Calif Constitution could be reamended (Calif constitution is amended and reamended all the time so, while it's a pain, there's nothing written in stone about it at all.). But I'm digressing. My point is that you get used to discrimination and you kind of expect it. I've lived in the Bay Area for 15 years and it's been so refreshing to not be treated like a second class citizen, but I'm always aware that a large part of middle American would rather see me dead or at least not there.
Heterosexuals don't feel that discrimination, yet my friends are very aware of directed at the glbt community, and since they have not had the experience of being discriminated against, it makes them really angry to see us treated in this less than human way. Where us glbt folks (I'm a monogamous bisexual actually though I don't worry about such details in the fray of prop 8) are too used to it. I need them to feel the righteous indignation that I've had beaten (not literally, fortunately) out of me.
I am profoundly grateful for our heterosexual allies.
