Racism is not a problem of religion guys! It's a problem of different culture in common, mentality, of just being different. Racism also has economical roots, so when people see some emigrant, who lives for government payments  (which are partly coming from citizen's taxes, as we all know) or works on an elegal job, they get annoyed by this fact. It's quite a rare thing to meet pure racism, like "I don't like aaaaall blacks! just because they are black (example)"
