It can be said music goes that way, but I would say that the opposite way is also true. because the two ways united in a particular harmony fosters a sense of common identity, and you only need to look at things like the eco essence and the solidarity from notes, tones, vibrations to see that music brings people together far more than it divides them. The moment something serious actually happens in music, the typical reaction is for everyone - including the opponents - to rally round and show love to each others.
