The problem is that giving him unnecessary exposure will definitely create much more young commies.

The question is, where are they getting these people. Unless they are our people, which I doubt, then it's none of our concern. Let SJWs become commies. What of it?

A lot of the youth have very favorable views of socialism.

Most youth, and others, have no idea what socialism is. They think welfare state capitalism as in Denmark is 'socialism'. Actual socialism is bankrupt.

Having them learn about the Soviet Union and the Holodomor will do more to help push against marxism than signal boosting Vaush.

If we are talking about such unintelligent people that they would support Vaush, I do not see how you are going to get their sad excuse for a brain to learn about Holodomor. Besides, they likely have a readymade response that "socialism in Denmark" did not lead to any such thing.
