there are no "pro-lgbt" bourgeoisie. there are bourgeoisie opportunistically pretending to care about the plight of marginalized groups for the sake of making more money. I suppose there are lesbian, gay, bisexual, transgender, queer, intersex, asexual, etc. people among the bourgeoisie, but their "solidarity" is going to start and end with people in their class. Ellen can sit down with George W. Bush precisely because his homophobia was never going to materially affect her. His homophobia was only ever going to affect working class LGBT people, because the bourgeoisie always make themselves the exception to their own bigotry (see: Cheney's daughter). That's why rich catholic men fly their mistresses to countries where abortion is still legal. They are the exception to their own rules and bigotries, their solidarity is fake and doesn't extend beyond their class, and their rhetoric about human rights is opportunistic and profit-seeking behavior.

as for bigotry among the working class, it is the result of bourgeois indoctrination. A divide-and-conquer strategy. Yes bigotry can be interpersonal, and the result of purely individual prejudices, but in the aggregate it is a learned social behavior that is the result of a system rather than purely/simply the moral failings of individuals.
