“But-but-but... the Constitution!” ... No. Seriously, no. Stop treating the Constitution like it’s infallible. It’s not. The Second Amendment was poorly worded, and it needs to be re-written. Badly. I once dated a fool whose sole argument in favor of owning guns was "even though it's in the Constitution?!"
Don’t worry everyone, I’m sure some of GM’s one-issue assholes will be along presently to remind us that an amendment passed 200+ years ago by slave-owning misogynist pricks is more sacrosanct than these lives.
