I am not Catholic. I am Episcopalian and have serious differences of opinion with the Vatican, e.g. on birth control. Actually most US Catholics agree with me on that.
I am not blind to the failings of out of touch old men in the Vatican. I have fought for victims of child sex abuse.
I am also not a coward, so I don't slander the world's 1.3 billion Catholics or lash out at random Catholics when I'm really angry at the SCOTUS nutjobs.
This reliably causes assholes to think I'm Catholic.
