Well, to a white color worker, yes. But to someone working a blue collor safety critical industry, that's going to come across as rather tame. (And I do get annoyed when people get overly focused on language and forget that _we_ are a safety critical industry. To a first approximation, all the critical infrastructure throughout the world runs on Linux, stuff that doesn't is a rounding error, and all the testing and validation that exists only provides a safety factor. We have to have our shit together, and that does need to come first). That aside - my point isn't about what should and shouldn't be allowed, it's just that norms are arbitrary and it's not the best argument if you want someone to change their behavior. > > We're a community, no one is employed by anyone else here; we work > > together because we have to and we have to figure out how to get along. > > We work via consensus, not appeals to authority. > > As a community, yes, things are different.

And I think we're all aware at this point at how that sort of thing does drive people away, so best not take it so far people start to consider you a liability - or one way or another there's going to be an "or else". This place functions by making people feel respected and valued for the work they do, so a degree of respect and consideration is required.
