As far as people who want to ban guns outright, there are certainly people who believe fervently in that, but I think a lot of those people don't necessarily think about the enormous financial and human cost of doing so. They look at a country like Japan and say, "See, if we ban guns like they did..." But ultimately if someone seeks to confiscate guns by force, they're advocating for violence because there are many, many people who would kill and die for the 2nd amendment. Most people don't see it that way, but in practice that is what it would come down to.
I agree that a lot of extreme pro-gun folks are opposed to any and all sorts of compromise. And you're right that there is a significant contingent "Earth is 5000 years old" people in there. But there are a lot of liberal gun owners, white-collar gun owners, and everything in between.
Either way the discourse is not helped by coming to the table with intentional falsehoods designed to scare people who don't know better. Whether it's 'Obama is trying to take over Texas' or 'Assault weapons are to blame for mass shootings'.
