I think certain types of guns should be harder to obtain, a lot of mods should be regulated differently, and I think the age requirement should be a bit higher. Mass shootings are too much of a concern. Kids shouldn't be stressed about going to school.
But I'm technically in the pro gun camp. I think Americans have a right to protect their homes/land/property/families with violence, if they feel like they don't have another option, especially if the government tries to enter their homes unlawfully. I feel like if you're able to responsibly own your guns, it doesn't matter to me if you own 1 or 50 of them. I also think most adult Americans should at least carry a pistol, especially women, who may struggle to physically defend themselves otherwise.
