I'll maintain that protests aren't the best way to deal with these and just turn into an attention circus.

I'd just recommend that normal people attend these in mass when they come to their communities and play the roll of an unreceptive audience. Don't clap, don't cheer, just fill up the seats and sit there, with notepads, and write down the sorid details of what exactly they are doing. They'll get skeeved out and won't come back.

And if you see anything inappropriate or borderline illegal. Just all go file a report with the cops and start an investigation. The cops might be able to ignore singular reports. But if you get 100 people who attended one of these events all filing reports that is difficult to ignore.

I don't think sign waving and yelling and otherwise engaging in "activism" does much good besides create buzz for the media to get rich off of.
