A Drexel professor is threatening to take “all necessary legal action” after a tweetstorm against “white supremacist patriarchy” following the Las Vegas shooting got him kicked out of the classroom.

Drexel professor George Ciccariello-Maher said in an op-ed for the Washington Post that he is on “administrative leave” following a “smear campaign by conservatives aimed at academics.”

The tenured professor blames his suspension – not on the tweets – but rather on “illegal threats of violence” after Fox News and other outlets wrote stories on his tweets, in which he blamed the Las Vegas massacre on “Trumpism” and a “narrative of white victimization.”

It's the white supremacist patriarchy, stupid.
