Well, I dont know much about most outlaw motorcycle gangs.
I am reading a true story of an undercover ATF agent who infiltrated one of the most heinous of the OMG (Mongols) in 1998. Its called "Under and Alone" I think. Its a good read.
Based on what I know of the Mongols they are nothing but a criminal group of ex cons and drug runners, gun runners and violent types who would best be left alone or locked up.
They really cannot be called a motorcycle club at all but a "gang" just like the crips or bloods or any of the hispanic gangs in the barrios of East LA.
The process of becoming a full "patch" in the Mongols means proving yourself to the existing members by committing crimes and earning their trust as a "prospect." If a motorcycle gang exists for itself and for violence and illegal endeavors I'd have to say they are best left to their own devices as they give motorcylcing a bad name.
If a motorcycle club exists for the comaradierie of the sport and to further riding than that would seem fine. Once again if the primary purpose of and or to earn membership in a club requires one to be a party to illegal activities or violence than thats just wrong.
