She is speaking with emotion, and not with any kind of rational thinking. We do not live in an ideal world where if you ban something, it all goes away. If you ban guns, only the law abiding citizens will give them up. Then only the criminals will have them, just like they do with drugs. Maybe when a criminal has a gun in your face and you gave up your right to own one long ago, maybe THEN you will think that it was a dumb move.
I can only wish that something bad happens to you so that you can learn.
