Other countries have some element of 'gun culture' - shooting/hunting clubs etc. It's not something I'm interested in but I can understand the allure, sure. I think what bothers me about home is the widespread nature of it. A substantial portion of the population owns guns and I guess I just don't quite understand that. Perhaps you are right in that there needs to be a change in attitude around guns, sure, but I really do think that it should at least be some more regulation. But I admit my opinion might be different if I grew up around guns and had respect for them as an outlet/hobby - I guess I don't. Thanks for the context though, definitely something to think on.
One thing that is important to remember, as well, is that almost everyone will reasonably agree to guns not being able to be resold, or needing to have ID and criminal background checks before buying a gun. The problem is that the debate constantly gets phrased as TAKING THE GUNS AWAY! by the people who really are disrupting progress for little reason but political support. Not necessarily that existing US gun culture opposes any restriction. That's my experience though.
