Joanna Watson's self delusion speaks for itself.
She tells us an anecdote about being 'married to a nation' then later in the film happens to mention she 'used' to be attracted to women. It's one thing to deny yourself happiness but to dedicate your life spreading the very intolerance that makes you ashamed of who you really are is an abomination.
If you saw someone on the street speaking gibberish, waving their arms about crying or rocking back and forth on a park bench like an abused child you'd cross to the other side of the road to avoid them. So why do people buy into it when it's done en mass in a church? You wouldn't walk into a mental institution and say "wow, these guys know what they're talking about!" I just... don't... understand.
