To go back to the original subject of the thread, it occurred to me that Christianity has a similar but different problem of its adherents engaging in evil acts contrary to its scriptures. Only in Christianity it's not violence, it's greed.
There are hundreds of preachers here in the U.S. who have become incredibly wealthy by preaching and practicing the exact opposite of what Jesus taught, under the name "Christianity." They preach a prosperity/magic gospel, that God wants you to be rich, and the way to become rich is to donate to them, because God will reward your giving by making you rich. I know it sounds ridiculous, and has no biblical support whatsoever, but believe me, I'm not making this up. Ordinary people, many of them poor, send their little checks in to these TV ministers, and they add up to $ millions, which they spend on jets, mansions, yachts and the like.
It's kind of funny because Jesus taught to give everything you have to the poor, and these people get the poor to give everything they have to them!
Anyway, it's comparable. It's not True Christianity, but it is actual Christianity, and it's up to Christians to do something about it and persuade other Christians and the world that these evil sham representatives of their religion have traveled far from the true teachings.
