Tumblr SJWs use the sociological definition of racism (which is meant to be used on large groups of people and cultures, not individuals) which is power + prejudice = institutionalized racism
So when people accuse them of being tribal for hating white people, they can say "actually i can't be tribal because i'm not white stufflord"
When in reality, when you as an individual are prejudiced, you are tribal, by definition.
From there they go onto say that since white people benefit from institutionalized racism, we are automatically tribal, which is illogical
