What you should read is that there is so much obvious evidence, easily available, that asking for more of it can only be interpreted as bad faith. I am certain that there is no evidence that fits your standard, because short of "Study: Schools taken over by radicals" you would not accept it. A scientific study like this would never be funded, even if this were a question for science (it isn't), for many reasons.

A google search of the relevant terms would turn up dozens of egregious instances. Have you looked?
