I also remember someone getting fired for using the word niggardly in a meeting. According to your logic, that makes him a racist, end of story, who deserved his punishment.
It's ironic you are antagonistic to PC culture, yet display exactly the same behaviour yourself - what someone says is not important, it's whether or not someone manufactures offence from it that counts. Victim culture.
Whether it is from the right or left, this victim culture is ridiculous. I just don't get the point of actually trying to be offended by innocuous things. Each to their own I suppose.
