I'll take a shot at a spicy reply: they aren't wrong, at least not completely. Having a lot of guns won't stop the government from taking your rights, but it does limit their options. That's why American conservatives have to bend over backwards to make sure you know: if you're an American who identifies with gun culture, they are unequivocally on your side *. The current administration would love to restrict gun ownership, but they're still afraid of losing the support of that bloc. And I think it's at least partially because they have guns.
