Another Reason to Dislike Habermas

I'm no fan of abstruse Marxist philosopher/sociologists, so I found this point rather amusing:

I remember reading a response by Habermas to a critic, limited to the statement that he refused to discuss with an individual who quoted Hegel from a secondary source.

I remember seeing a documentary on Jacques Derrida, and he was asked what one question he would like to ask Ludwig Wittgenstein if he were alive, and he said he would ask him about his sex life. Philosophers are pretty loony.
