I don't think it's racism, the roots of traditions are many and how they are to be passed shouldn't change much. By that I mean that it should be held in such a way that it doesn't make a city collapse, but clothing, imagery and words, shouldn't change in such a way that it transforms a tradition. It would destroy the heritage and create something different, and not necessarily better. Honestly think this is something were the groups that care for a and including society, should accept and concede, that this is cultural heritage and it should remain as is.
