Well of course they do. It fits their fantasy version of reality. Blaming the actual murderer doesn't fit their imaginary universe where people are controlled by inanimate objects rather than the other way around. These people meet the definition of delusional disorder.
This is why you can't reason with them. You can't bargain with them because the have nothing to offer and they NEVER keep their promises. Anti-gunners (and after the last few month of the outpouring of liberal hatred for Trump I'd say liberals in general) can only be destroyed. They will not quit until they are dead or we are dead or we are totally enslaved.
You pretty much summed it up accurately there. We are at war with liberals, but we haven’t faced that fact yet.
They apparently have, if their rhetoric is to be listened to.
