Why?
There is also a cadre of cranks here on FR who do naught but Creationist-Baiting . Sometime, look through the postings of the average evo. Are they interested in the Supreme Court, taxes, gun control, abortion, etc? Nah. They're just here to seek out the barefooted snake-handlers and give them a good snarl.
The IDers give the evos a run for their Grant Grubbing, and I say that's a healthy exercise.
