Re: "Why are conservative student organizations routinely referred to as "hate groups" and bastions of "white supremacy?" 

Because the liberal media are directing our attention to it, and not directing our attention to the white supremacy established by liberals.

Decades ago liberals created a monument of sorts that still operates in a stealth way to produce an insidious racist effect -- of maintaining white supremacy -- worse than any produced by a conservative or a bronze confederate monument.

And they have not told black Americans about it.

See:

This is not what you think it is. 

It may be too shocking for some.
