An ally is someone who stands up for what is right. They can either be leader of an organization, or just simply a friend who supports you no matter what. Ayvazian defines an ally as: "a member of a dominant group in our society who works to dismantle any form of oppression from whish she or he receives the benefits." This definition is possibly the best definition that I've heard on what an ally is. I do consider myself an ally. The only downfall is that I have not done anything to help the cause.
