that doesn't really work very well any more...the people willing to participate in a race war dwindle yearly...some kids buy into their parent's paranoid bullshit, and some realize their parents are just full of shit. they go to school with kids from all kinds of minorities, and get to know them on a personal level. it's a lot harder to hate someone you know, whose customs you understand, who you know has no intention of "stealing" your job, your woman, or your way of life...
there are still entirely too many people who would jump into it with both feet, but there are less of them every year, and they're starting to be held accountable, legally and financially, for the damage they try to inflict.
i'm not a big fan of folk music, but this song has been true since it was written, and will probably be true till people vanish from the universe
