The danger, I think, comes when people take this and twist it to actually mean something "in the real world". I think there are healthy ways to express your misogyny, racism, bigotry etc...and there are unhealthy ways to express this. Music, I would argue, is perhaps one of the most healthy ways to do this.
Pretending like the world is a perfect place, like we don't have biases etc, is more detrimental than a song about "bitches and hoes" from some rapper. imo..
