as to call them 'christians', I like to refer to those azzhats as 'CINOs' Christians in Name Only

Or doesn't that advance the narrative in the direction MSNBC would like it to go?

Doubt it.

The Community of Welcoming Congregations
On Earth Peace Academy
New Community Project
More Light Congregations of the Presbyterian Church USA
Open and Affirming Congregations
Supportive Congregations Network
Brethren-Mennonite Council for Gay, Lesbian, Bisexual, Transgender and Queer Interests
Open Table Cooperative

These are a few of the organizations and congregations that I've personally been involved with, so it's necessarily an incomplete list.

I am certain that the United Church of Christ, the Metropolitan Community Church, the Unitarian Church, and the Progressive Baptist Alliance do.
