Empirically, none of that is true. The state of gun ownership in the states is proof of that. Cast iron proof I'm afriad. You have far more gun crime than we do. Your gun laws are far more liberal than ours. It's an open and shut case.
I know you will now say you won't be dictated to by your governmnet, and that you can't believe how people in Europe allow such a thing. But who protects your second amendment rights? Do you think that the amendment equips you to protect it yourself? Do you think, that even if you did have an RPG, you'd be able to protect it if the government decided to revoke it? It never fails to amaze me how some Americans are naive enough to believe the second amendment is something that the government doesnt protect, and instead believe it is they themselves that protect it.
