I think that after the 2008 financial crisis and the following bailouts for the people who caused it, a lot of people got fed up, and occupy wall street was born. Occupy was a class based movement: the ultra-rich vs everyone else. And then something happened, and suddenly everyone had to be divided by every other attribute imaginable - race, sex, gender, disability - class just wasn't as important. Instead of the 1% vs the 99%, the 99% was divided by all those attributes and fought each other over whose issues were more important. Then it quietly fizzled out and nothing was accomplished.
The 1% must be so happy watching the 99% squabble amongst themselves over who's the most oppressed. I think that most, if not all, of the major political/social issues today should be viewed through a class-based lens _first_; everything else should come second. But the users of this tool cannot have that, and here we are: everything is about race/sex/gender and nothing is about class.
> If you are a white European, you will have a hard time seeing racism, compared with people who are not white.
That is a racist statement in and of itself, and you do not even know whether I'm a "white" European, let alone the fact that "white" means just as much as "black" when it comes to indicating the culture people grew up and live in. Since I can only assume you are not a racist I assume you made that statement because it is part of the current narrative - it is called standpoint epistemology [1], part of critical theory - without really giving it some thought.
If you agree that racism is used as a political weapon it is only prudent to make sure you do not unwittingly make yourself become a part of that weapon.
Yes, people tend to react differently to people depending on whether they are from their own group or from the outside, up to and including to telling them to "go back where they came from". This is said to Polish migrant workers in western Europe, to Palestinian migrants in Syria, to Koreans in Japan - in all cases you'll be hard-pressed to find any "racial" differences between the groups. It is chauvinism, nationalism, protectionism or just fear of being overrun by "the other". It is not racism and should not be called such, specifically for the reason you yourself mentioned: racism is being used as a political weapon.
The Dutch knowing nothing of racism is super fucking rich. Read your own history books.
