Listening to the people in this thread, it appears to me the solution is so simple: we need to outlaw insanity.
What's that you say? We can't legislate away insanity? Dang ok, well maybe we should just make it so that you can't buy insane automatic rifles like the ones used in all of these mass shootings.
Also, I hear people like MTG advocating for more guns in schools and for teachers to be armed. That's fascinating. If we trust teachers to have guns in school, we should also consider letting them be responsible for picking the textbooks and novels in our kids' curricula. Wait, what? The same voices have been attacking teachers for picking certain books over others? Ugh, this is confusing...
