At least one Christian leader already advocates the murder of his opponets. Here is a quote from Randall Terry the founder of the anti abortion terrorist group called Operation Rescue:

"When I, or people like me, are running the country, you'd better flee, because we will find you, we will try you, and we'll execute you. I mean every word of it. I will make it part of my mission to see to it that they are tried and executed." Terry Randall, quoted from "The War On Faith"

you know actually i agree with the judge, that teacher crossed the line. in a science class a teacher should be able to present reasoned, supported arguments for why creationism isn't a valid scientific theory. but for a history professor to just rant like that isn't very useful and isn't his job.
