Well, don't expect this to be just limited to web presence, anon has a lot of ability to physically assemble people. They had some success with that at the height of the scientology protests, and I would say their ability to assemble has improved since. And of course anonymous protests are always hilarious, because no blow is too low for those desensitized by the trashpile of the internets where anonymous lives and feeds most weekday evenings. Expect no quarter given
I've had some reservations about some previous Anonymous gatherings, but if the Westboro church was actually active here in Canada, I'd seriously come out and join 'em for a stakeout.
