I guess it depends on what concepts you are willing to let go of. If you think Jews have some kind of holy right to land occupied by other people, yes, things are goig to be complicated because you also want to protect your ability to think of yourself as a good person, and that precludes you from supporting ethnic cleansing and genocide

If, on the other hand, you see Israel as a settler-colonial project no morally different than the Dutch in South Africa or the British in North America or the Spanish is South America or the Belgians in the Congo, it becomes a much easier ethical calculus.

There are plenty of Jews who view Israel as the latter, and the fact an identity "makes things complicated," points to self-interested decision. Just like being white makes the concept of removing barriers to employment by black people "complicated", or being a man might make supporting female rape victims "complicated." The fact that a choice might not benefit a group you identify with is not an argument in favor.

And, yeah, nobody should listen to "as a mischling jew." That's 1/4th Jewish.

Plenty of Jewish people interpret the slogan and promise Never again to refer to all genocide, not just that committed against Jews. Israel has been committing human atrocities for a while now, but under the authoritarian Netanyahu administration, they've burned the nuance right out.

Israel has become the monster it was once afraid of, and once promised never to be.

feel their culture and their right to exist is under attack and the actions are justified

And I feel like I deserve a harem that sucks my dick every hour. That doesn’t make me nuanced, it makes me a dumbass. Pretending like the history matters at all is just a way of justifying evil actions to yourself.

That's fair, and I'm sympathetic to that fear and that concern, but for all the nuance of how it got to this point and why there's still too much support, I do think that the reality as it has become has removed all nuance from the situation as it currently stands.

Israeli soldiers are engaging in genocide with all the gleeful torture and killing that is associated with the crime. They need to be stopped, leadership needs to be punished, and the everyday people need to be deradicalized.

A lot of people's anger at the calls for nuance comes from the fact that we keep being told there's nuance and that we need to be sympathetic to israel as they commit horrifying crimes and not only is nothing done to stop them, people in western nations are being prevented from stopping our governments and institutions' assistance to them.
