racism is not: i hate this group of people who have the power to hurt me and continue to hurt me.
Actually hating races as a group is racism by the standard definition. I know that tumble people have their own definition (as well as delusions that a whole race of people has hurt them or have power over them).
hating a group of people is prejudice; but when the group being hated is in a position of power (oppressive) it is not an act of prejudice to dislike/hate that group.
