Being racist implies you are prejudice against someone based on their race. A moment of lapsed judgement doesn't make you inherently racist, as doing something dumb doesn't make you a dumb person. Not all racism bans have racist intentions. So by me saying I don't think they're inherently racist, I'm not referring to those who were being racist, rather the ones who used the word vaguely with no intent to harm, etc. Context matters. A word is not racist, it's how you use it.
