Sane, intelligent and educated people know that "an absence of evidence isn't evidence of absence".
So then why are you blaming mental illness, of which there is an absence of evidence in Vegas OR Uvalde?
I think it's because you can't conceive of someone committing a mass murder who isn't mentally ill, but committing the mass murder isn't an act of mental illness, nor was mental illness what prompted the mass murder and we know that because there are millions of mentally ill people who don't load up on weapons and ammo and go on a shooting spree.
So since it's not mental illness, it's gotta be something else...and I think that something else scares you because if it isn't mental illness, then it's the fuckin' guns.
