Why cant the mongols and hells angels just be friends and share a common interest in motorcycles and riding?

Why can't the Shia and Sufi, Sunni get along with their common interest in same diety and main prophet, holy book? Why can't the north Koreans and south Koreans get along with same language and background? There is more to the 1% clubs than motorcycles and riding, there is economic and social status, political issues in conflict- and some leadership, survival issues involved. Next you'll say Outlaws and HA should get along despite history.

It's just the nature of a 'closed group' to go into extremes of human behavior. Some are drawn to such groups / some avoid them for the range of behavior they inspire.

'Closed groups' are almost never about 'the motorcycle' ...Life goes on.

Because typically, these street gangs are NOT just all about riding motorcycles. They are criminal enterprises and into selling drugs, prostitution and all the other illegal activities that typical street gangs get involved in. The fights these gangs are involved in are typically about turf or territory

Where's the fun in that?

Who would you give your drug money to?

The main problem is turf protection.

Ask them.
