Justin. Who wrote the Bible is way too much off-topic for this Recism thread. You can start another thread, if you want.
Equating racism and tribalism is ON-topic, though, because "tribal" prejudices (which encompass national and some cultural prejudices) are lumped in with racial prejudice by the laws of many Western countries. Think of placards reading Whites Only, No Mexicans, No Arabs... All those would be prosecuted under anti-racism laws, in some countries.
The word race itself has several connotations. There's the human race, the Caucasian race, the Nordic race, the Jewish race, and so on and on. But there's actually no black race or white race or Christian race. Racism has come to mean prejudice of any kind, for practical purposes.
