Racial bias in Austria

Recently, I have heard from friends and felt that some racial biases really exist in Austria. Not always Austrians, but sometimes "foreigners" in Austria do. Most of the time, it might just happen during the discussion or chat, but we don't sense that. After you go home, you think of it and feel uncomfortable.

Maybe it's because of the barrier of language, it is easier for people from different countries and different cultures misunderstand each others' meanings. And it's always the people who have less self-confidence lose first.

As a result, people who have the same background tend to get together. I don't think it's a good idea, so I try to make friends with everyone, understanding their ways of thinking. However, I am not quite sure if I can make it because I also still like to acompany with Asian people.
