I'm sure there are individuals who think that way, but I don't think it's a significant number at all - certainly not among elected representatives, political commentators, or anyone else with a significant amount of power to actually affect gun legislation.

It's odd to me that so often when someone refers to gun control of any sort, people like the commenter I responded to immediately respond with "Well you can't just ban all guns." The vast majority of the time, nobody is actually proposing that we do so. It's over-defensiveness at best and strawmanning at worst.
