"Offended" may be too harsh a word, but "annoyed" would certainly apply to me and "uncomfortable" to a number of professional software developers I know. I don't know many shrinking violets, but that doesn't mean you want to be hit over the head with (stupid) sexual metaphors when you're working just because the library developers are incapable of reining in childishness.

Like, by itself, not a gamebreaker or anything (for me that would be a weakly typed language--though I've encouraged my little brother to play with Moai, another Lua environment, in the past), but given the choice I'd probably go with tools with a culture that encourages a bit better judgment.
