Note the casual endemic anti-White racism "white people define" as if all white people hold the same opinion. Imagine if you took out "white people" and replaced it with "jews", or "blacks".
I don't think anyone would have an issue with it. Generalizations aren't bad as long as you don't treat them as fact. When people say, for example, "Arabs always" or "Persians always" or Jews always" etc., they usually mean "most Arabs always" or "most Persians always". But these statements are, of course, generalizations of a situation and should not be treated as fact. Pants of dog has an element of truth to his statements. Most people, including whites, believe that racism is the feeling of racial superiority over another person.
Furthermore that isn't "anti-White racism", that's chauvinism.
Thinking your tribe is slightly better than others is mild racism. Thinking your tribe is the chosen people is extreme racism.
If, by tribe, you are referring to the modern American political party (which you must obviously be referring to) then this is far from racism. Tribes in a modern sense aren't ethnically motivated, they simply are set of interconnected interest groups who share a common goal and opposition. These interest groups may use varying ethnicities as scapegoats but this isn't due to ethnic reasons, this is due to the ethnicities themselves being part of another tribe.
If thinking you're tribe is the chosen people is extreme racism wouldn't that make Israel the most racist and amoral place on earth? It's entire existence revolves around that idea.
