Presumably tired of making the lives of veterans' families miserable, the loons of the Westboro Baptist Church have decided to picket a mosque in Dearborn, MI. It's listed as being the largest mosque in the states, so I'm thinking the vast majority of attendees are just normal people trying to get by. Unfortunately, as with any religious community, simple statistics means there are likely even more of the wacko kind of Muslim nearby.
In other words, they seem to have taken on a target that's much more likely to hit back.
