After the Oklahoma City bombings a lot of different militia groups with far right Christian ideologies sprang up thinking it was the end of the world and the government was going to round them up and throw them in concentration camps. These groups were often quite violent-minded and had the clear intention of performing violence against the government. There were several arrests in Michigan near where I live, one group was going to blow up an expressway. The newest incarnation of these whack jobs are the Hutaree, but really the Hutaree aren't all that different form the groups that sprang up in the 90s.

You may call people like them and Fred Phelps fringe or radicals yet they all practice Christianity and operate as Christians with ideologies THEY seem to find in the Bible. The fact is, it happens in every religion. The Hews have their radicals, the Hindus and Buddhists have their radical (Buddhists invented suicide bombing), and Christians and Muslims do too.

Again, the best way to avoid radical ideologies is to discuss the new mosque/s with the leaders of the group and make sure they are on the up and up and then help them integrate into the community. Instead, in many places no one in the community is even talking to them or discussing what it is they want to do there, they are just protesting because of some rumor that bunches of mosques are centers for radicalization - something pretty much not true.

Then again, scared people historically typically act stupid. I guess some things never do change.
