LMAO... Perhaps he should look up "Dignity" as in the LGBT catholic organization... [dignityusa.org]
Considering the T and the Q are all about shaping the external world to conform to internal beliefs, Id say its absolutely possible for them to be catholic or anything else. The LGB part, maybe not so much.
I considered becoming an Catholic before I left the dark side. I'm glad I avoided that train wreck. I know there LGBTQ Catholics in this world and Archbishop is a big dummy if he thinks there are not. The gay community has the right worship an imaginary god or not, just as much as the straights do.
