He's about as far-left as they come. I think I came across his page after trolling through Taryn Fivek's page. (Remember her? Emma Quangel?) She's always linking to the most crazy stuff happening on the left, for example, "J20 Resist! Protest Trump's Inauguration in Washington D.C."
Anyway, he's trying to weasel out of his comments calling for a "white genocide," although killing off the white race is pretty much standard fare for hardcore leftists. Drexel, his university, is right to distance itself from his commentary.
See Inside Higher Ed, "Drexel Condemns Professor's Tweet." (At Memeorandum.)
The dude's protected his tweets now, although I think just yesterday they were viewable. He's worried about getting fired. He should be.
More from Sierra Marlee, at RWN, "Drexel U RESPONDS to Prof’s Tweet “All I want for Christmas is White Genocide”."

And a sample of the dude's far-left commentary:
