Actually racism is when one race or set of people look down or believe another ethnic group is inferior to the other.
No, it isn't. You don't need a whole group or race of people to have racism. Just one individual would do. They also don't actually have to think another race is inferior. It's entirely possible somebody could be racist out of jealousy due to thinking another race is superior to them.
Racism is just treating people worse due to their race. Just like sexism is treating people worse because of their sex.
