Minorities for the most part are devout Catholics or Christians and revere marriage as a holy sacrament and view it as one of the monuments of their faith.
Obama, as I have always believed from day one, is an atheist and therefore has absolutely no religious scruples, principles or convictions ergo he has no moral anchors in his life by which to guide him and as such has abandoned the sanctity of marriage that so many of his race hold dear to their hearts.
Maybe Obama made an unconsidered step, or maybe this was coldly calculated. There still has to be a whale of a lot more black voters out there than gay voters, and the blacks typically don’t like the gays horning in on their corner on affirmative action.
Blacks and Hispanics mostly are not supportive of the gay lifestyle. The preachers tolerate babies out of wedlock but not being gay.
