The presence of the gun did not cause the murder. A psychotic evil woman caused it. Blame the availability of the guns all you want. Libtatds do the same.
Since you seem a little dim, I'll repeat what I said in a more simple way. If a drunk gets behind the wheel of a car and kills someone in a wreck, is pointing out that the drunk had shouldn't have been in that vehicle the action of a "libtard" who is "blaming the car?" No, it isn't. Try thinking instead of repeating mantras and slogans for a change, it will do you world of good.
