Thank you. This needed to be said. A lot of it comes across as downplaying and very reductive. Jews in America today do have privilege- they are often white-passing, and they are a "model minority"- more educated on average and their per-capita income trends higher, so they are rarely under fire directly as blacks and Latinos are. However, handwaving away someone's Jewishness as "oh, he's a white man" or "Jews aren't a race" is absurd and offensive, too. Jews are still targeted by hate groups on the right. We are a week removed from a dozen Jews being gunned down in their place of worship.
All this doesn't mean that Sanders can't be racially insensitive, or that Jews can't be racist- of course they can be! Just, it's important to approach issues with sensitivity and consideration and, in a topic where we are complaining about a Jewish politician being insensitive of our issues in America with racism, to not handwave away his minority ethnicity either.
It's a political calculation, is what it is. There is a reality, which is that to win important states you have to win over a white majority in those states. And alienating that majority will cost you the presidency.
Note that no one is saying that Sanders is racist, in this thread. I don't think anyone genuinely believes that he is. But I think this isn't an example of, "well he misspoke" or that he has a more positive outlook. Sanders consistently alternates between being blind on racial issues, where he should be sensitive, and dismissive of racial issues, when he should be attentive.
