You are wrong there, Evil. Even rights guaranteed by the constitution have limits, as you have even admitted. This includes religious rights, free speech and even the right to bear arms. Assault weapons have been banned before. The government (ie. Lawmakers) places these limits for the betterment of overall society.Guns are a tool, just like you said. They are only dangerous if used improperly. In the hands of a bad person, fertilizer and fuel oil are dangerous. If you don't use a chainsaw correctly, it can be dangerous.
Why do I care that people that I don't know want to curtail a right so fundamental to the foundation of this country that its founders wrote it down second in the bill of rights? That can't be a serious question.
The democrats do want to take our guns away. Hell, a couple of them have even admitted it. See Senator Feinstein, the senior senator from Californistan.
They just won't come out and say it, so they infringe a little here, and infringe a little there. It's called incrementalism.
The whole "you don't need a _______" argument is BS. You don't determine what I need. I determine what I need.
While you may personally want to open carry an RPG, laws can be constitutionally passed restricting your right to do so. While there is zero chance of ever passing a total ban, despite what a few far Lefties want, the recent rash of mass murders must be addressed. Eventually people will have had enough. I don't know what solution will be, but it will certainly include increased restrictions on the ability to easily produce mass murders.
Please note that I understand there is nothing that can be done to totally eliminate this risk, but simply to make it more difficult.
