If you run into thugs attempting to stifle free speech at a townhall meeting, just look for the union label:
Just check YouTube for “SEIU ACORN violence (or thugs) at townhall” for slews of videos.
Or, if you want some easy-greasy-sleazy money and can buff up your physique while dumbing down your intellect to the level of slime mold, you could apply to be an “SEIU organizer” and go around playing thug at townhall meetings, yourself!
