Not to mention that there are different kinds of racism we lump together under one label. Someone can think a certain race is, say, bad at math and still be racist even without disliking that race. Someone can also hate a race without believing they have some inherent inferiority, and that's racist. Similarly, you could simply decide to support your own race at the expense of others out of a sense of loyalty without even disliking other races and that's racism too.
