I wouldn't say they are abandoning pacifism with this song. The line "You don't have to be PASSIVE just because you're a PACIFIST" says it all. There are ways of fighting back that aren't physically violent. But it does show a shift from a kind of "we'll do our thing, they'll do theirs and eventually we'll win" thinking to a more proactive approach.
