Define "long history." I went to a therapist for over a year when I was a pre-teen after my parents divorced. I learned a lot of good anger management and coping skills from those sessions. Should that bar me from owning a gun?
I don't think anyone other than severely mentally ill people should be barred from owning guns.
By "severely mentally ill," I mean people who we used to put in insane asylums. People who have been violent, people who are exhibit psychotic delusions or other obvious symptoms.
Were you institutionalized? Were you psychotic? Did you hear voices? Did you use violence against others? If so, then I would answer your question with a "yes." If not, "no."
Of course, I believe that sane people should be allowed to arm themselves. I also believe that people who are clearly mentally ill (it's not that hard to spot such people, at least if you're not constrained by the now-thoroughly-politicized DSM-5) should be institutionalized for their own protection as well as that of society. If they act out in ways that endanger others, they might be shot.
I believe Steely Tom left off the "/s" tag. As you know, there are innumerable laws already, they just don't seem to work. So then, the real solution is to add stronger laws that can do nothing to reduce the risk. But at least we can feel better about ourselves. :)
