I'm going to give an honest answer, but i fully expect to be downvoted and demonized for doing so. Nothing I can do about that, but op, you want an honest answer, this is it. I'll also add that I would 100% consider myself leftist, in fact, extremely leftist in most of my views. Why the hell would my username be what it is and why the hell would I be on lemmy if I wasn't... anyway... here's the answer since you asked for it:
The large majority of jews I know, including myself and my family feel like this current war is the fault of Hamas. Oct 7 doesn't happen, this war doesn't happen. We also are continually annoyed by the fact that most people on the left, constantly refuse to acknowledge that Hamas has been pushing this war forward non-stop for decades. All you have to do is look up number of missiles launched at Israel since 2000 to see that. People no-doubt try to rebut this by saying "but Israel has been stealing territory". My constant response to that is they have been taking territory to establish buffer zones to enhance security. As almost all of this land has been taken after conflict. Israel even tried to give back some of this land, but was then attacked again, and had to take land back in order to protect itself -- But eventually our conversation just goes back to why this is even happening and we are always frustrated by the fact that any argument from the left condemning Zionists always begins in 1948 -- when in fact the troubles of the region started hundreds of years before that. This pre-1948 history seems to never be brought up however. So the blame is always cast 100% on jews and all of the attacks on Jewish civilians within Israel are never ever given the time of day.
It's incredibly frustrating and scary, because the narrative is fully turning into "jews are evil", and there is nothing any Jewish person can do about it. Jews are never going to willingly leave Israel and Hamas is never going to stop trying to eradicate jews. There are only 16ish million jews on the planet and almost 2 billion Muslims. There is no way jews could ever win this propaganda war. I think a lot of jews who feel they are on the left side of the political spectrum are too scared to even speak about their feelings on Israel/Palestine at the moment, because they know they are going to be vastly outnumbered and demonized, by those they would usually consider friends, with anything they say. So most of us are silent on the subject because we don't want to be ostracized.
I will end this by saying, we of course feel bad for civilians caught in the crossfire, but we feel like Jewish civilians are not given that same respect. The sentiment we get is that Jewish civilians seem to deserve it.
