Why are you Spanish darn racist?

I'm just watching these youtube videos and seeing this poor Samuel Eto'o character, very good player indeed. Your people throwing bananas at him and making money chants, for the sole reason of the dude being BLACK. I mean come on now, he's on your side, so why are people against him? Plus he's a great player. I've never been to Spain, don't really plan on it. But I don't see why all the racism is necessary. Yeah I've heard there is lots of black and muslim immigration coming to certain European countries, but still... no excuse. I think all this racism towards these players is more jealousy because they are so successful. Whats your reason? How would a non-white really be treated in your country?
