--they usually don't bother "civilians", only each other. While some of the activities in which they engage are illegal, such are only engaged in by willing participants. On the other hand, most of the activities which politicians do involve the unwilling---
If you haven’t read hunter thompsons book I recommend you do. Very interesting. Especially the part where he attempted to intervene when a hells angels member was slapping his woman around, they almost beat him (stomped him really) to death.
And if you're in a bar and they show up, make a quick exit. They do tend to get frisky after a few beers and might take exception to the color of your shirt or something.
Substitute urban gangs for bikers and it sounds the same. The activities they engage in (mostly drug dealing, primarily meth, and gun dealing, including the outfitting of urban gangs) lead to much tragedy to "civilians". I have seen personally the damage they can contribute to when I lived in East County in San Diego, many lives ruined because of meth. Frisky? If causing mayhem and pain to innocent people because of the color of ones shirt or how you looked at their ol' lady is "frisky", then they are no better than a thug doing the same because they don't like the color of your skin. These guys are romanticized by shows such as SOA because they have a "creed" and purport a love for the good old USA. They are scum and lawbreakers that use their numbers to intimidate people.
To paraphrase William F. Buckley, I'd rather be ruled by the first 100 biker members picked randomly from the nation's roadways that by any Democrat and most Republicans.
