Find a new country.Nah forreal like wtf are we going to do?
We can’t keep raising children in this environment. It’s only going to get worse.

But seriously, given the state of the SCOTUS, and the fact that the average American is truly worthless, because they are dormant in the head and refuse to participate in any meaningful way, makes it such that the likelihood of any serious legislation passing in America to prevent this from happening is slim to none, it's definitely not happening in your lifetime.
Last proper response to a mass shooting that I can recall was Ardern's response in NZ. Now America is a bigger mess in that regard but changing things like that starts with the people, and the people of NZ didn't need another mass shooting to occur in order to get their wits about them. America is just overrun by stupid and selfish people, they pay the price every day.
