No one's screamed or jumped up and down, but certainly folks have pointed out when I've said or done something racist. Eg., when Charles Brown was upset with me for calling him "Chaz". Plenty of other instances of it.
I'm not clear on why it is anything to be upset about. We live in a racist society. Racism isn't this reified thing hulking around, out there, reproducing itself free of social practices and interactions. Individuals reproduce (and change) social structures. Not surprisingly, every single one of us says and does racist things.
While everyone professes that race is socially constituted, this seems to be completely undermined by a firm attachment to the notion that racism is so deeply etched into the body of someone being called racist, then they are marked forever. Talk about marking of bodies!
