>There's another definition, which is talk that's designed to maintain & reinforce the institutionalised power structure among races.

I generally think it's safer to frame in terms of the effect (which you mostly do) than motivation. Even if someone has no ill intent, and simply talks a certain way because they haven't really thought about the issues, their speech still does harm.

Agreed. Some things can be a joke (ie they are funny, they make people laugh, they are told with intent to entertain, not hurt) and can be racist. This is why "but it's just a joke" does not mean the thing isn't racist. Sometimes when someone says a racist joke, the discussion then turns into whether it's funny or not, and if it passes the funny test, it's not racist.

But it doesnt matter if its funny! It matters if its racist!
