The GP asserted that "The very idea of guns make some people crazy - for or against, usually against." and you responded with a totally hyperbolic re-frame of the argument, insinuating that pro-gun people come from a place of wanting to "own an arsenal of any weapon of my choosing, the bloody bodies of children be damned".
I'd say you've just proved their point.
Why don’t you go live in Mexico for awhile. You can be under constant threat of kidnapping, crime, etc. you can always call the police if you have a problem. Guns are illegal there.
