I wonder why he chose 'vulgarians' for the studio version? I prefer 'vegetarians', personally.
--the one reason I can think of is that he is perhaps talking about his love life. Maybe what he is saying 'at last I am born', means that he (or the person the song is about) has found a love of some kind (with or without sex) and the he is addressing the 'vulgarians' who speculate and swap gossip about him and his personal life. I don't know, just a little theory I came up with after hitting the 'post reply' button.
