&gt; I'll support people carrying guns on campuses, and the "good guys with guns" bullshit, if you'll support universal conscription and basic training for all high school students.

I think the vast majority of firearm owners would 100% support marksmanship training for all high school students, perhaps with the option for anyone to choose to opt into archery as a substitute. Gun owners as a rule are generally very much in favor of training and education in general, not only for the sake of safety but also because people fear what they don't understand.
