Just goes to show how stupid but yet how deeply ingrained racial hatred can be ... Polish people are European and look just like white Brits, yet here they are being hated against.
Racism is an insidious disease, it's like a cancer that doesn't go away, it just tricks you into thinking it has.
Some people just do not have the brain power to view themselves as a human being, everything must be broken down to them in very simplistic terms (ie: I am a part of this nation/ethnic/religious group) they cannot comprehend anything bigger than that. It's basically tribal thinking that we haven't evolved out of.
The world today is too complicated for them, they are like an outdated computer trying to run a modern OS without enough RAM and processing power.
People say they "only" hate X/Y/Z type of people, but even if you remove that group then they'll just hate some other group. Hate is something is an unquenchable thirst, if everyone on the planet was the same race, ate the same food, worshipped the same religion, etc. etc. we'd still have wars/xenophobia over the same shit, just we'd invent new stupid lines of division, like people with freckles or brown eyes or something arbirtray are now lesser and then we'd start the cycle again. It's pathetic.
