Sure someone could bring in a knife and stab people. But the culture around guns (toxic masculinity, using violence as a means to win an argument, etc) are all problems. And at this point the guns are definitely the main problem. We can look at celebrations in other locales and the rates of violence are lower. And most other ‘first world countries’ have stricter rules/regulations on firearms. Trying to act like guns are part of the problem is just burying ones head in the sand. Sure other factors play into the violence, but when you can easily get a firearm and wish to hurt others it’s a lot easier than pulling out a kitchen knife.
