I think you misunderstand me. I have never owned a gun, fired one exactly once more than 20 years ago (Boy Scouts), and advocate for more gun control (not less). I would be totally useless in any realistic fight. The argument has some merit though, in that it is as yet unclear how much it would matter.

I don't think that unclear merit outweighs the very clear and data-driven drawbacks. I just prefer to engage subjects like this in a charitable manner.
