It's called "holding them to their own standard". You know perfectly well what would happen to Senator Lisa Murkowski if she (for example) were to accidentally say "nigger". She'd be pilloried, assaulted, hounded from office ... all for offending the perpetually offended ...

Perpetually Offended Councilman Marion "you're all racists" Barry.
I think it's absolutely hilarious that Ol' Crackpipe Barry can't seem to help making racially derogatory comments ... including using racially derogatory words ... and he's being held (sort of) accountable for it.
