It's not a double standard, it's a law.
You can be racist legally. What you can't do is:
- Close your business to people because of your racist beliefs.
- Fail to hire to people because of your racism.
- Prevent children from being educated in schools because of your racism
- Deny housing to people based upon your racist beliefs.
- Act out violently against people because of your racist leanings.
- Establish any facilities under the guise that they are "separate but equal."
- Demand that violent actions be taken against people because of their race.
If you don't like Jews, okay. If you hate the blacks, alright.
If you say "Hey let's gas the kikes again" then you're in the shit.
