The pictures themselves are fine. It's the fact that the posts are very similar, paid, and pushed to the front of a feed in a time when an ethnostate wearing the Jewish identity is carrying out a genocide on a captive population. It feels, as OP said, inorganic.

Of course the pictures could also be read as a reminder of what Jewish resistance really stood for, which would conversely carry a distinctly anti-Israel sentiment, and the optimist in me wants to believe that. I can't see the comments on the posts, so I have no way of knowing for sure.
