I have had the good fortune (?) to see some of these people while driving through Topeka, KS. They were protesting outside a church on a Sunday morning. I pulled over to ask what they were all about, knowing full well their history. One man gave me a weak response, basically telling me that they hate because God hates gays and loves dead soldiers. He also said that the priests inside were child molesters. When I asked why they thought this, he said it was because soldiers are dying and gays are getting married. When I asked how the two could possibly be logically connected, he returned to his statements that gays are destroying the world and that the priests inside are molesters.
I tried to reason with him, stating that while some church leaders have abused their positions, not all have and they also preach love. He would have nothing to do with it, and he also started accusing me of being "one of them". Some of his friends came up too, so I decided it might be best for me to drive off...after telling them that "Hey, I'm gay and you are really only making this world a sad place."
They are brainwashed into thinking they are truly right.
