At first I thought this was irrelevant, at best a distraction from the serious topics that need to be addressed, such as freedom vs security, the importance of the second amendment, how we as a society treat the mentally ill.
Then I considered his words and I did some research and it turns out he was on the right track he just didn't take the idea far enough. Allow me to sum up firearm history. Around the third century the Roman Empire adopted Christianity. A few centuries later the Chinese invent the first firearms. Since then firearm deaths have increased roughly 2.9 billion percent!
The only rational conclusion is that our rejection of European polytheistic religions and religious philosophy caused this tragic event. To prevent future gun violence we as a nation must return to worshiping the Polytheistic gods of our ancestors. Obviously not all of them, that would be chaos. I'd recommend the Celtic gods but I'm obviously biased since I'm of English/Irish descent. A strong case can be made for the Norse gods since their movies tend to gross higher in the box office.
