Obama Friends-Marxists, Structural Feminists

Republicans have been critisized for using the word socialism and Marxist, but Obama said this in his  own book. 

The Democratic presidential candidate wrote in his memoir, “Dreams From My Father.” 

“To avoid being mistaken for a sellout, I chose my friends carefully, “The more politically active black students. The foreign students. The Chicanos. The Marxist professors and structural feminists.”

I don't know why anyone would want to be friends with Marxist Professors but I have never been a fan of many Professor's liberal ideas. That is just me.
