Got a creationist coming to your town or school? A commenter from Oklahomans for Excellence in Science Education left an excellent summary of how to counter these travelin’ frauds effectively. The key is simple: recruit. Get the information out. Don’t let them come in and babble unopposed or with an audience imported from the local fundie churches — get informed people there, and the creationists will crumple easily.
Notice that this isn’t about suppressing their information (or even expelling them) — it’s shining the light of open public criticism on their shenanigans.
