yeah. when you mentioned it earlier, that was totally tough one -- and I'd forgotten it when it got buried under the pile of stuphage. i don't like my formulation either. Carrol will help. :)
still, there's something different. it's a group of people saying, you don't treat us, your consumers, properly. So we're boycotting you. In this case, the actual employees of the bus systems were, if Robin D.G. Kelley recounted the whole story, perpetuating and holding up the system: shooting passengers,. beating them, pistol whipping them, refusing to pick them up.
this is different than boycotting a product because of their treatment of workers. the boycott is to get a company to stop treating consumers in a socially unjust way. if, for some reason (an SA hypothetical methinks) the workers weren't perpetuating this racism - like the scabs -- then I wouldn't boycott. but i think that would be highly unlikely.
