Degs:

The LW is white. His/her employers are white. If he/she objects to the comments her (screw the gender neutral stuff) employer can fire her and ADMIT it's because she doesn't share his racial attitudes and under current law she has no case.

It's not illegal to fire someone of your own race who does not share your racial attitudes, or who doesn't like your "jokes". Maybe it should be, but it ain't. There's no whistle to blow here.
