Why should this matter to the LGBT Community? Because we are just as affected by broader social-economic trends as everyone else.
One of the lies that anti-gay bigots repeatedly say about the LGBT community is that we are spoiled, pampered hedonists with more than enough disposable income to influence politicians with campaign money that "hard working 'Christian' families" cannot afford to give.
The truth is that the LGBT is just as likely to be poor as anyone else.
LGBT youths who have been cut off from their families are less likely to receive financial support to pay for college and get a higher education than their straight counterparts.
HIV positive men can tell you what negotiating our for-profit health care non-system has done to their finances.
Because of DOMA, we do not receive any of the federal benefits of marriage, meaning gay and lesbian couples are poorer than their straight counterparts.
Anti-gay bigots want to pretend we do not raise children and want no government recognition of our families, and our children are poorer for it -- and not just theoretically.
LGBT around the world depend upon an American government that believes that our human rights are important all over the world, at home and abroad.
Also, the Koch Brothers and other far right-wingers buy and sell politicians to implement economic policies to not only to create a "rigged market" that transfers ever-increasing wealth to the top 1% and their decendants, but also helps to elect anti-gay politicians who will use their time in office to pursue anti-LGBT legislation. Getting special interest money out of politics matters, especially from the bottomless pockets of corporations and the superwealthy who give money to anti-gay politicians, if the LGBT community is to see its inalienable right to legal equality become manifest in America.
While it is true that there are some gay activists who seem to care more about their "access" to the top 1% than actual "progress" for our community and believe we should ONLY focus on overtly "gay issues" like marriage equality. In my opinion, this is a very myopic look at the world. The countries with the greatest social justice (and marriage equality) for the LGBT community (Scandinavia, Canada, Netherlands, etc.) also have the greatest economic justice for ALL their citizens. Martin Luther King, Jr. knew this all too well. Social justice and economic justice go hand in hand -- which is why the success of the Occupy movement should matter to all of us, LGBT and our allies, and deserves our full support.
As the Occupy movement moves from having stationary camps to more organized activism, I implore you to get involved with a progressive movement in rescuing American politics from Fox "News" and the corporate-financed "tea party". The coalition building this encourages will make LGBT equality MORE likely in the future.
