I don't think you have given an honest answer.

Fascism is just a modern riff on imperialism, which is old as the hills. As such, it is definitely something that should be studied and discussed from every possible angle.

And if it is a mistake (it is), you should have faith that these college kids will, upon closer examination, outgrow the sieg heil phase, and come out with a better understanding of politics & history.

OR, just keep suppressing everything with credentialed word salad, Streisand the hell out of it, and make it so that even the Jewish kids are denying the holocaust.
