Depends on the behavior and even the consequences are not as "clear" as you make it sound because reactions to behavior can be rather subjective. Context actually matters even tho it's too often ignored these days in favor of generating drama.

It's a factor way too often ignored with this issue: If "hurting people's feelings" will become a crime, then we will see no end of regulating "undesired behaviors" because people get their feelings hurt in the most subjective and unintended ways [0].

So much about "obvious examples of racism".
