There's two levels:

1. Hating someone for an attribute they can't fix or were born with is wrong. For example, skin color, sexual orientation, or being Jewish*

This is wrong because a Black person can't stop being Black, a gay man can't stop being attracted to men. In other words it's not the fault of the person.

2. Hating a person because of a belief is different. Hating all Nazis is bigotry but almost all people wouldn't consider that wrong. Hating all people who think Israel should be a country is also bigotry. The big difference is the person has control over their belief.

What standard? Who is setting this standard?

#------------ * Being Jewish is considered both an ethnicity and religion, it's complicated. Hitler didn't care if jews converted, his definition was ethnic. In this conversation I'm considering it an ethnicity.
