Don't comment on anything related to any conflicts immediately East of the Mediterranean lest you wish to be in an ad hominem "debate".
This problem drives valuable content away from the site, unless the lurkers up/down vote based on the value of a contribution (and not their personal opinion) or the mods step in, which is still seemingly rare.
As a (sometimes) lurker, when I see a comment on the middle east I say "wow even if I studied this conflict I would still have trouble having an opinion here" and skip over it+the replies. I also can't tell if the person said something so ridiculous that the ad hom isn't out of line.
I frequent Lemmy, Mastodon, and Threads. I feel like this is true in any of the three. Occasionally, I'll wade in, but more often than not I regret it.
This is especially true on Threads where the algorithm sees you arguing with someone saying X and then says "hey, you must want to see more posts that say X." I finally realized that all I was doing was feeding the algorithm and stopped replying.
