Doesn't matter if you're completely okay with it - the point is that both are obviously racist. Better to recognize what it is and nip that sort of thing out early...
Really kind of depends on what you're trying to accomplish. If you're trying to change cultural norms and sunset meaningless stereotypes, then discussing social biases is probably more likely to get you progress than telling everyone that they're racists.
If, on the other hand, your objective is to gain some sort of elusive virtuous superiority by highlighting the assumed moral failings of other people... then I suppose that always referring to it as racism will fill that emotional need quite well.
