That is not what is being proposed. At least not here in Ohio where red flag laws are actively being discussed. Our Governor's proposal makes specific reference to following due process and there needs to be a preponderance of evidence. Even after your court hearing, it is only a 30 day ban. The State has to go back to court to keep your guns longer to get a 6 month ban, then every 6 months after that.
I don't really like the restrictions being imposed either, but reported on the news this morning was that the mother of the Texas shooter called the police and told them she was very concerned about her son's rhetoric, actions and recent firearms purchases and she wanted to know what her options were. The cops said she had no options because he was of legal age to buy the gun.
Stories like that make you pause and think. Not every non-criminal that can have a gun, should.
I agree with that, to the point of how do we figure out who gets to make that call? Who determines what kind of talk crosses the line from being angry with the world and wanting to go out and commit mass murder? The issue we face here is that we have a 1st Amendment and a 2nd Amendment. One protects speech and the other firearm ownership. We run into problems when we try to shut people down before actual harm is committed. At the end of the day all a person can do is make sure they're prepared to protect themselves and their families, and if we are going to take action, let it be to figure out what's going so wrong with a person that they commit mass murder and find a way to fix it.
