I totally agree with this. I'm no fan of Maher—I've never found him funny, and I just don't really like his style—but I do think some of the speech-policing has gotten way out of hand, so I'm sympathetic to some extent. On the other hand, with a word like the n-bomb, maybe just, like, don't say it. In all but a few instances, it's probably not necessary to your point—even if your intention is not racist, even if your intention is explicitly anti-racist—so just consider whether it's really worth it.
