Probably a VERY long time ago, given that the song’s title itself contains a derogatory word. Shame that the melody is admittedly quite catchy. But we must preserve as much of the past as we can, both the good and the ugly sides. Today’s youth, including my own generation (Generation Z), have gotten far too soft when it comes to topics we’re uncomfortable about. Some of us are even trying to dismantle any relics of bygone eras simply out of shame or guilt from our ancestors’ actions, when it’s not us right now who are to blame. To hide or destroy this item would be like pretending the time that it’s a product of never existed, as with other things like banned animation and such.
