My family is always making racist comments and it really irritates me.?

[**anna**]

They make comments about how other cultures shouldn't be allowed to wear what they do and how they should convert to western fashion or go back to their country. When there's a bad driver they say "go back to your country". When there's a crime on tv they say "oh guess what colour he is". They know it bothers me a lot but they continue to do it. I've gotten to the point where I don't even attempt to argue anymore, I just keep my mouth shut and steam. What else can I do?
They also make brainless comments about homeless people, how they need to get a job and they joke about throwing food out the window of our car to them. I don't find it funny at all, I find it really offensive. But they don't care that it bothers me..and they know it really bothers me..help?
