Should racist insults be illegal?

[BradleySec24]

7. Not illegal, but socially unacceptable.

Might I add to the list of racist slurs being hurled on social media, when ethnicity is used as an unspecified pejorative slur, increasingly used against Americans without any connection with the targeted group, as if it doesn't doesn't change the offensiveness of the racist act.

For example: Jewish troll, Bibi's stooge, Netanayhu lover...

..and:

Russian troll, Kremlin stooge, Putin lover..

Some people have a blind spot, while they know one is wrong, but have a strange ability to do say equally racist comments to another group. Hitler didn't differentiate, he was an equal opportunity mass-murderer in the East, so don't be an ass.
