Hardin sounds like a very normal guy, and I would also say that I sound like a very normal guy, but for some reason when he cold calls people and talks to them, they help him. If I cold call people and talk to them, I am reminded that I am committing felony telephone harassment and have been instructed many hundreds of times to stop calling. This is a joke, but no really I am apparently very unpersuasive.
That is to say, my default position now is to let him talk to anyone I actually want to care about my plight anymore.
As far as his courtroom debate behavior I do not know. If we're truly lucky we'll never have to find out and the Supreme Court will just give us what we want
