Could someone explain to me why I got an infraction for this?
And first, I get the whole "no offensive language because there's kids here" thingy. But is that really an offensive word? I could have used one of many slang version of the word, and yes, sure, that would have been offensive. But that? I'm pretty sure no one has really found that word offensive since the 1950's. You can look it up in any standard dictionary. 13 year old kids learns the meaning of that word during sexual education in school (or at least we do, in my country).
Actually, I'll keep the infraction if you insist on it, but could someone just, please, assure me that we aren't living fifty years ago and that this is an okay word.
