I think you misunderstand hate laws.
The US has no hate laws. The laws, however, do cover hate crimes.
Essentially a hate crime, in the US, is an added punishment to a crime committed out of hate.
Ie., if one assaults another, they get one penalty. if one assaults another and calls them a racial slur, then get a worse penalty. (that's a simplified example.)
Germany's hate laws were laws segregating, demoralizing, and outlawing the freedom to exercise religion, targetted mainly at jews.
These sound like completely different things.
