Over three hundred million in the country... ceaseless spewed hatred from media, online memes and the educational system. Mix all that in a cauldron of anti-maleness and gun free zones and you get guaranteed results.
I understand shotguns are in the mix here.
You forgot to add in the liberal's dream, viz. single mother whores having children indiscriminately because they don't need a father figure. Their bastard children growing up without morals, values or ethics. An utter sense of depravity and lawlessness.
Liberals have only themselves to blame for this chaos.
Of course, Hitler loved lawlessness which was what gave him the ability to consolidate all power in himself. That's been their game all along. And it's not over.
