Your opinions on what should and shouldn't be, regarding gun control legislation in the U.S., disregards the legal context of what is and isn't constitutional there. It also disregards the fact that guns can't be regulated away, any more than illegal drugs. And a call for stricter background checks should start with an analysis of current background checks, which is something I've never seen from advocates of this position.
Do you really want to start a discussion on how two words, "gun control", will or will not solve all the school shootings, and violent deaths? Take a look at the school shootings in Canada, the London murder rate compared to U.S. cities, the lives saved by self-defense with guns, and get back to me.
How about sticking to what you're good at?
