Religion

The religious progressives I know are members of the United Church of Christ and the Metropolitan Community Church.

The Massachusetts UCC came out early for marriage equality, and I think performed the first same sex marriages in the nation. It was a leader in the anti-apartheid struggle, and a supporter of Rev. King. It routinely condemns homophobia, racism, sexism and classicism, including among conservative Christians. Just an aside: it also invited then Senator Barak Obama to address its annual meeting, giving him I think his first ever national platform. President Obama, BTW, is a member of the UCC.

The MCC was founded as an LGBTQ friendly Christian denomination in the 1960s. It obviously condemns homophobia, and also all the isms listed above. Since a good portion of its members are LGBTQ people chased out of more conservative denominations the members I know are quite vocal in their denunciation of, for instance, Southern Baptists.

Perhaps if you cited some specific examples of progressive Christians giving religious intolerance a pass, I might be able to comment with some specificity.

Edited to add: I notice the OP talks about "progressive Democrats" rather than progressive people of faith.

My reply remains relevant though, in that the progressive Democrats I know, religious or otherwise, seem to have no problem denouncing what needs denouncing. Which progressive Democrats are you talking about? Elected leaders? Rank and file?
