If I grew up in your shoes, I'd probably feel the same way you do.
I agree with the poster who said the black community has an important bond, some kind of togetherness. Yes, we have problems but we do support each other.
I'm not sure, but I think you are referring to me. But that was the sense I have gathered over time.
People I don't know have wished me good luck and felt proud of me b/c of the academic success i've had just b/c we're both black or because of the community I came from(lower-income background).
HOWEVER, this is not something unique to the black community. There's a sense of togetherness for many ethnic groups... latinos, chinese, Irish, Italians.. as an oppressed group I would think gays would have more of an understanding and support for others. They don't really seem to though. Gays are often more racist(outright and subtlely) than their straight counterparts. They're not that accepting with open arms to minority groups as far as I've seen and I as a whole, I havent really seen them come out in support of women's issues, issues of low-income groups, or minority issues.
We just don't have that same bond with other Whites, even. It would be pretty unusual for, in the example you pointed out, for a White person simply to go up to another White person who they don't know, and give them all sorts of congratulations and that kind of thing. We are a Community, per a label based on our skin color, but we really aren't a Community at all.
We have some Church group communities, like Blacks and Hispanics, but those are pretty small and rare in the big scheme of things. Most of our Church goers leave Church on Sunday and they don't see each other until next Sunday, or the Sunday after that.
We keep to ourselves and are more bound by individual friendships that are made, as opposed to sticking together as a whole community. Many, many families out there aren't even close to each other.
But I speculate since Minorities do have that sense of Community amongst their race, they interpret that the reason they don't see it amongst Gays, is because "White Gays are racist". And I dare say that the overwhelming number of Gays are not racist. Although you don't see or feel that sense of "Community" with White Gays simply because we don't really have that same sense of "Community" and togetherness like minorities do. That simply isn't the way we do things. We are more individual and have less of a sense of loyalty to each other. We're basically out for ourselves ... but at the same time that doesn't interfere with our ideals for doing the right thing, especially when it comes to voting.
So I guess I am saying when I see people say that "the Gay Community hasn't made me feel welcomed" (presumably we are talking about White Gays) .... it simply is because we aren't really that together as a real "Community" ourselves. We're out there. But I dare say an overwhelming majority of us don't have meetup groups, or go out in groups, or anything like that. But we do have our individual friends, and still believe in Gay Rights.
But again, its understandable for a minority to question that if they see and feel the sense of togetherness in their racial community, why they don't see the same in the "Gay Community"? And the answer is because it isn't because Blacks are being shunned. Rather, it's simply because the entire sense of community you have amongst Race simply is not there with White Gays, in general. Like I said, we don't even have it with each other. We are simply out there on our own and try to do the right thing.
