PS I will say I don't think it's just institutionalised racism causing these problems.
Sometimes it is just total ars^&*!es that cause the problems. If they didn't discriminate against "thick lips and curly hair", they would find someone else to be unpleasant towards. Perhaps they might discriminate against people of Irish ancestry, they might want to discriminate against plebs who didn't go to the right sort of school or perhaps they like Ginger jokes.
Not behaving in that sort of way is not "political correctness". It is human decency, or perhaps just good manners.
