How many religions teach that showing love for God means destroying people who don't believe their particular dogma? All of them.
None of them believe in a human's right to control their own life.
They ALL think that they are the only ones on earth who worship god correctly, which gives them the right to order other people to obey THEM. "God told me to tell you to obey me. Or else you're gonna die!"
They are all insane, no exception. Constantly begging former members to return, just shows how badly they want the kudos and brownie points (recognition) from their bosses. Which in turn shows that probably you are never going to be as important to them as that recognition from the congregation.
