I would would not go into this by underestimating the DA, he may not be as helpless as you think, and there's a decent likelihood that when this comes to trial, he'll be putting up a fight, and to the extent that he's allowed to by the judge, he'll be showing stuff about your public persona to the jury, including your posts here. And while there's some chance the jury might listen about the bug hoax and pharma takeover, there's almost no chance they'll listen to many of the other intricacies that make you a unique individual, and that, in the eye of the general public, make you at best a nutcase, and at worst someone dangerous. All the DA has to do is show the jury a few of those and their brain will completely shut off to anything you have to say or argue.
My suggestion would be to not open that door for the DA, my understanding is that he may not be allowed to bring in evidence about your personal life until you bring that up first.
Best of luck and I'm here if you wanna discuss anything regarding this.
