Conservative sources are good, but I always thought that conservatives based their opinions on the evidence, and liberals based theirs on "feelings". I like evidence.
I am certain that I can find plenty of the NEA members and plenty of your fellow employees whom will side with you. Hands down the majority of people employed by the public school system will say there is no fraud in funding or diagnosing children with ADD( even tho we have some of them here admitting there is).
If you feel it is wiser to believe the NEA and in the conversations you have had with less than conservative sources, who work in the field in question- over what I have shown you from conservative sources with track records of running successful business and supporting conservative ideals- that is your choice.
