You’re so hell bent on defending your right to have a gun that you forget the definition of words. Again, if they were necessary then you wouldn’t have people around you that didn’t own them because all of them would be dead, that’s what needing something implies. Stop eating food for a couple of months and you’ll understand the difference between desires and needs.
Just because the ownership rate is going up doesn’t mean people need one, it could simply mean people are scared and the population is divided so they try to find a way to reassure themselves, just like you’re doing, but the need is to solve the underlying issue.
Like someone who’s depressed, they can start taking anti depressants and live like that for the rest of their life, but what they actually need is help to solve the underlying issue, if that doesn’t happen all that leads to is more and more people on anti depressants.
