He may have been from a Republican family, but both his friends and family said he was on the far left. Hell, he was a very outspoken leftist, who was ALWAYS on the side of the left when it came to ANYTHING political.
Face it, the Kirk Killer is a far left extremist, and you delusional leftists want to push him away so you can stop yourselves from asking if you're gonna be on the right side of history. You don't want the responsibility of knowing one of you guys did such a blatant act of violence, nor do you want to acknowledge your side on the aisle is simply more violent than ours. I'm not even American, and even I can see you guys are statistically more likely to engage in political violence than the right.
