I would not be surprised if, from when "man" live in caves, he and she have taken part in lampooning, ridiculing as well as extolling others due to differences and it has probably contributed to the strong psyche that exists in humans today. The alternative seems a grey, drab world. But, until these activities become illegal, live with it and ignore and treat with disdain those that are not your cup of tea. For example, there are not, if any, marches around Westminster calling for the head of Bernard Manning but at the same time I doubt there are any members of ethnic groups support his performances by attending.
