As I said, I do not believe you are ever honest in a debate, and you do not fail to deliver dishonesty.
You're the one who blamed mental illness for gun violence, before readjusting the parameters later on.
But the problem is that by even invoking mental illness as an excuse for gun violence, you ended up inadvertently asking the question of how do we determine who is mentally ill before they get a gun?
The only way to do that is mandatory examinations that will result in many gun owners losing their guns.
You can't just toss off "mental illness" and then abandon that excuse when asked to contemplate how we address it....I mean you CAN, you'll just look like an asshole who doesn't want to have an honest discussion.
