There is absolutely nothing wrong with saying that our schools shouldn't be teaching this crap, and advocating for the termination of those teachers/professors who do.
On the contrary, I think it is incumbent upon all supporters of liberty to speak out against the insanity and inanity that virtually defines modern Academia, for it is poisoning rather than enriching the minds of our children.
With private institutions, those paying school tuition have every right to demand accountability on the part of professors and administrators. In the case of publicly-funded institutions, it should be up to the taxpayers to determine whether their funding should continue or be reduced or eliminated.
In neither case should speech ever be opposed or silenced, and that goes for all sides.
