Ok, Yoshie, I agree with you about these criticisms. However, I think you are pushing the same remedy that the Left has been trying for decades. This remedy revolves around recruitment of people of color into Left organizations and tokenizing their presence in the organizations. These same Left organizations then proceed to browbeat other Left organizations or groups because they are "so white." The activists of color then end up doing most of the media outreach and public speaking, in order to give the organization a thin veneer of diversity. Ask yourself why so many Left party newspapers were always parading Mumia Abu-Jamal's on every cover? It's because they thought that doing this would give them street cred and would help them recruit people of color. It's not like these groups did very much shitwork on Mumia's case--I remember meeting after Mumia support meeting where these opportunists would show up to sell their newspapers splashed with Mumia's face, only to not stick around to do the shitwork.
I think different approaches are needed. While I would welcome any person of color who joined one of my groups, I wouldn't want them there simply because we needed to have more persons of color to be kosher with other activists. I think white radicals need to consider the importance of building *ally* relationships with political and community groups that are dominated by people of color. The focus would be on building support networks, mutual aid, and solidarity, instead of getting everybody under on party banner.
Yes, Left movements do worse than these institutions, but why is that so? I've got some ideas, based on my experiences, but I'll save that for another email.
