Actually, "defending" was probably the wrong word, but conservatives claimed liberals were "defending" that whackjob Islamic guy in Oklahoma who beheaded a lady by claiming it was workplace violence, so maybe you should criticize them as well.
Calling me a "libtard" and "completely retarded" was ad hominem, especially since I am not a liberal or even progressive.
I apologize for misusing the word "defending", however there is no question that it was an act of terrorism.
