I am not a lawyer, and nothing on this site should be construed as legal advice. I'm just a layman with an opinion.
The difference between gun control activists and gun rights activists is simple: gun rights advocates know what they are talking about, because they have depth of knowledge and expertise about firearms and pay attention to the issue. Gun control advocates, for the most part, don't know anything about guns, aren't interested in guns, and only pay attention to gun issues when the latest blood-dancing press release arrives. There's no sustainability.
