I reject your premise that loving Israel means being unable to tolerate any criticism of Israel's actions. I'm a citizen of the US; I would argue that I'm critical of the US because I love it, and want to see it improve. That's why I'm so critical of our military and our foreign policy. We commit a lot of war crimes; it's a huge problem. I'm also critical of our shitty healthcare system, our lack of social safety nets, our institutional racism, and so forth. As an individual I don't feel like I have a huge amount of agency to affect those things, but I do try my best, including voting and communicating my views to those around me.
So yeah, I think it's totally fine to be Jewish, and totally fine to love Israel. What I don't think is fine is being okay with every aspect of Israel's current actions in Gaza--in particular, the multiple instances of the killing of journalists, health care workers, and children, and the extreme restrictions on supplies entering the country. Those aspects are all obscene. The level of suffering in Gaza overall right now is unbelievable.
If someone takes offense at my calling those actions by the military obscene, I would argue that's not a matter of Judaism. That's a matter of rather extreme nationalism.
