Brothers
One of the reasons why biker gangs do not allow women or anyone else they do not see fit to enter their group is because of their principles of brotherhood. It is a very sensitive topic for them and one that they do not joke around with. Brotherhood is everything to these people.
Although women play a huge role in the personal lives of each member, they have to understand that the priority in their husband’s life is the gang and then their families. Nothing comes before the crew and this is why it is of the utmost importance that loyalty and brotherhood are maintained.
