It's pretty common - an activist collective gets together to meet about starting a campaign. Even though the group is relatively diverse, it seems to be that the people who are talking the most are those with considerable privilege. It's those folks (white, straight, male, rich, able bodied, etc.) that have to make sure that they aren't falling back in line with the status quo.
North American society is made for the privileged, with the justification that we live in a meritocracy. In reality, there are many different systems of power working to oppress certain groups, depending on what identities they hold.
