What do you think about me telling my coworkers that they're being racist against me because I'm white.
How exactly are they being racist?
They're just being nasty towards me, they have been picking on me at work.
If they're being rude and mean because of your race, you need to do something, but it would be wrong to accuse them of racism if there is no evidence.
Being racist is wrong and I won't allow it.
I understand your feelings. You could file a complaint with Human Resources, but that could backfire, depending on the company. Or you could find a new workplace, because dealing with these people might only make things worse.
