Without commenting on the reasonability of it, you may want to be aware that a growing population of vegetarian and female tech workers may find these offensive.
Beef dies in the wild too so DEADBEEF should not, I do not care if they want to use B16D1CC instead :) I can't see why CAFEBABE would be offensive though.
...And honestly I guess I don't care? If people are that mad about some levity then I probably do not want to work with them.
If you want levity, why not just use terms that aren't offensive? If you can't think of a joke without being sexist or misogynist, then that's on you - don't blame others for "not having a sense of humor"
I don't understand how any part of that applies to my comment at all, sorry. (I take it from the way you quoted it at me that you think it does.) "Flamebait" applies to the comment I was replying to, though, I think.
