Allow me to put in a word for Bowdlerization. Without the good Doctor and his followers, it could never have been said of Desdemona that she ".. played the trumpet in bed.."

Seriously, though, there is a huge difference between avoiding singing "all de darkies am a weepin'" and objecting to "To the begging I will go" because it suggests that beggars are on the scrounge. And as for "all persons", what about the perdaughters?
