The quote in title is from this article.
Stop eating this bullshit up.
You should support criminals and crazy people owning guns. That's crazy, thelma, you say? No, not really.
First one is sane-sane-sane-crazy. When does this switch occur? I dunno. But the sane guy can have a gun but the crazy guy cannot..but they are the SAME PERSON. So to argue that you do not want crazy people to own guns is crazy itself.
And criminals? If they are dangerous, they are locked up. Once freed, they can enjoy their rights again (note: gov't cannot take away rights as they do not provide them to you --- criminals always have their RKBA -- they are just locked up, separated from their guns during incarceration).
And being crazy should not be something that automatic disqualifies either. Those that are dangerous, too dangerous to be left out in society, due to their illness should be institutionalized until well enough to re-join the general population and, once done, have access again to their guns.
