He is supportive by the standards of the Catholic church. I wouldn't call him an ally... He is a welcome change though and it is nice to have a religious figurehead who cares about the harm and joy brought to people outside of strict doctrine. Esp considering most Christian doctrine on sex does not stem from God nor Jesus but from a mis-reading of people who mis-heard. Does not Paul condemn men and women acting against their natures and references the animal kingdom in this. This logic combined with modern understanding of sexuality in nature is actually a pro-LGBT message. Not that anyone cares. As my barber says, Haters Gonna Hate.
