Is Owning a Gun a Good Idea?

i think a lot of fantasies about guns pro and con are not surviving scrutiny. The policies i would want to see enacted, are more restrictive than any that anyone on the left is even arguing for. And yet, i find it very difficult to wish for a world without guns,. I'v just spent enough time training in martial arts and just studying human violence. On some level, i wonder whether we have a totally intolerable number of mass shootings.
