You found not racism, but ranting caused by frustration as you are writing it in your blog.

Clean, pure racism can be found not in the crowd and not in any pub, but in silent people's mind.

It does not hurt, it does not rant. It will only silently kill when it sense it's family in danger. A danger which is coming from a different culture. You can call it racism, but it remains natural instinct of subsistence.
