Okay as a person who is a huge SoA fan, as well as a person who knows multiple Hells Angels through association or indirectly, and a person who has met Happy, the real hells angel on SoA who happens to be from my general home town, the whole Hells Angel endangering the lives of people wearing SoA apparel or vests is either a very localized or miniscule problem. Most real bikers like them would not threaten their business or freedom (jail) over a person who is mimicking a TV show for a costume party, especially a TV show that is loosely based of their club, and also a very watered down ***** version of their club lol. Albeit HA members can be complete dicks, so long as you do not go out of your way to throw anything in their face or disrespect them they are usually of no bother to general people having a decent time. Though alcohol can greatly influence this on both sides of the spectrum.
