I didn't watch the video, read the article.
He never should have owned it. Sounds like a panic buyer too; I knew nothing good would come of that. If you feel so guilty you need to go cut up your rifle, yeah, you shouldn't own it. He also shouldn't be dragging the rest of us down with his stupid fucking argument either. The article (and I'm assuming the video) have one singular goal and it's so obvious, but I bet that'll get glossed right over.
So he chopped up his rifle. Unless he planned on shooting up a school himself he stopped exactly ZERO school shootings. He did get people to listen to his stupid ass though.
We need to spread our own stories about responsible ownership and use in America and stop letting big propaganda speak for us. The time of the whining guilt ridden over sheltered over paid over indoctrinated under educated hipsters is almost here. And it looks... Stupid.
