As i see the song Bobby does not tell us to kill them (actually it is a gril in the sample). As i see it, this song is about someone telling to kill hippies (most likely that kinda state he "battles" in all xtrmntr) and then he says that he got soul adn not money.
this song is almost as dirty&nasty as shouting "hey jesus, i'd like to smake sweet love to you on the altar right now!" - in church. halfway during a sermon. with lots of old people listening. and as ripelviejam already pointed out: when the bass drops, holy fucking yes.
