I would add that currently racism is used inflationary by all who think they are morally superior and flag anybody with the "racist" sign who is e.g. concerned about mass migration of foreign cultures and the negative consequences of it. It is this abuse of the term racism that prevents a true understanding of each other which leads to the big polarisation of left and right that we currently see. There is also the right to keep his own culture intact without getting entitled racist isn´t it.
