You are suggesting the two go hand in hand (we can either have the right to own guns or the right to not get shot). 99.99% of gunowners don't shoot somebody with them.
Your answer still isn't providing any sort of actual reasoning where the one or two number comes from as a reasonable amount of guns to own.
If your only reasoning is the right to not get shot, we should also make it so each person can only own 1 knife. Also we should limit everybody to 1 bat. 1 golf club.
See what I'm doing here, all of these items are ultimately designed for something else, but have absolutely been used to beat the living crap out of another human. So because humans have the right to not get beat up, we need to limit ownership of these items.
You can't look at every other country and say because it's a priviledge there to own guns it should be here as well. We aren't those countries.
Does the US have more fun casualties? Absolutely. But let's keep in mind that we are talking about 5 murders per 100,000 people.
Money can't buy happiness. Just video games, which make me happy.
