I invite you to compare and contrast Fred Phelps and his blathering rhetoric to three other Christian pastors.
Phelps
is a pastor, is he not? So we know that a few things must be true:
1) He passed seminary school, so clearly his doctine was judged sound by his teachers;
2) He was commishioned to lead a church, so clearly his doctine appeals to a congregation.
He's an asshole, to be sure. But he's also a legitimate Church leader. That's something that your religion is going to have to deal with. I don't suggest that he's the best Christianity could be; I've seen
that here. But he does represent very real attitudes and dogma positions within your religious community.
