Any time someone poses a "doomsday senario" and follows it up by asking for donations to help fight the evil, my Bullshirt Meter registers in the red zone.
If the post is correct, I would take a chance on a misdemeanor to defend myself, no questions. I do my best to not let anyone see that I am carrying concealed anyway. If some gung-ho cop, with xray vision, wants to haul me in for such crap, I would just have to go to jail. With BS laws juries aren't really interested in sending folks to jail anyway.
I live in Florida, and we still have a law on the books that makes it illegal to live with someone of the opposite sex, that you are not married to. (cohabitation law) I don't worry about that one either.
