Substitute legitimate gun owner, Christian, Tea Party member, Conservative, Jew, for Motorcycle club member and they would still cheer on, aid and abet, and help the police shove individuals like you and me in the cattle cars when the order comes down to do so.
In Germany in the '30s and early 40s and in Eastern Europe in the early 40s those of their ilk assisted the German police in rounding up and executing the undesirables each time the opportunity arose.
Nothing but anonymous agitators, not worth engaging for any purpose but entertainment, and one ought to avoid that because it just creates more noise in an already noisy environment.
Sorry. Those you want to substitute are into gang warfare at public plazas.
