I am sorry if you felt personally attacked. I hoped it was clear that I was expressing frustration with the dominant narrative of these threads, which always seem to be very tightly curated. Condemning Israel's every move is the storyline demanded, reaching its peak (or should I say depths) in threads like the one about bad things being done by the IDF, which positively gloated over them accidentally shooting the escaped hostages.
I understand that some posts are genuinely motivated by grief and pain, but insisting that everyone takes the same view - that whatever Israel does, the only possible interpretation is that they are evil bastards - is what comes across as antisemitic to me, especially in the circumstances. Reading some of these threads, you'd think Israel was doing it all for fun. In fact, just after 7 October there was a popular thread on here suggesting it gave Israel the "excuse" they needed to dive in and help themselves to all that lovely land. How that was allowed to run and run on MN I have no idea, but as a non-Jew and non-Israeli I was deeply shocked at this utter gaslighting. It's what stops me even looking at the Middle East forum generally, and I doubt I'm the only one.
Yes, Israel should be "performing better" and maybe they might have been better able to do so if they'd been planning this war, instead of responding urgently to horrific trauma. This is an army with plenty of unprepared kids who are going to make some catastrophic errors of judgement (as illustrated in the movie Lebanon, which is available without subtitles on YouTube: e.g. the situation at 14:50 onwards, which is explained by what happened earlier at 10:50 onwards). To me, that just makes the situation all the more tragic, and heaping on ridicule and contempt does not help to build a more peaceful world.
Going back to the swastika at rallies, to me the obvious meaning is reminding Jews of Hamas's promise to repeat 7 October until they're gone. Kind of a "remember this? plenty more where that came from" gesture. Not to mention a "Look, we can make this threat to you openly in the streets. No one cares. You're not even safe here."
