> I want you to think about how you would feel in a hypothetical about Chinese people.
I'm not the person you are asking this question of but, after reading your comment carefully in full, I would like to answer on behalf of myself:
I would feel absolutely no differently about any individual person of Chinese ethnicity or citizenship than I did before.
Personally, I try to distinguish between the individual and perceived collective associations. And I try not project my personal opinions about global politics or my personal prejudices about a country onto individual friends and acquaintances that I hang out with at a local pub in a completely different country than the one we're discussing.
My operating definition of "racism" is:
"The religious belief that you can know the contents of an individual's mind and heart based on superficial characteristics - such as their skin colour, ethnicity or country of origin."
You can bring your "nuanced" opinion of Israel into it all you want to. But to project that onto an individual in the context of hanging out with a group of friends fits my definition of "racism" exactly. And this would hold even if one were to, hypothetically, concede your opinion of Israel's actions entirely.
Your post is a great example of why people so often brand attacks against Israel as "antisemitism." There is nothing wrong with being critical of a government and its policies, or of how a war is conducted. But to project those opinions and feelings onto an individual who is living in a completely different country and who has nothing to do with that conflict other than the fact that they hold citizenship or ethic affiliations is another matter entirely. One is "nuanced" opinion, possibly even objective if the individual is trying to be. The other is trying to mask and justify bigotry and prejudice behind an heir of intellectualism.
