There was a Ukraine War thread that got locked (similarly) back in 2023.
It was from then that the "emotional" thread was created (for thoughts and philosophy on the situation?), and also a "junior reporter" one (for facts). Perhaps to try to limit the tendency for hyperbolic intenseness to spoil discourse.
Ironically, the newsy one has been forgotten (postable, but might need necroing if you want to add to it), and the other one we see is active and perhaps a majority being based upon news. (Depending on your strict cut-off from "here's a link" to "here's what I think about that".) Possibly it can officially 'absorb' a bit more emotion due to it being offifially open to that. But actively probing the unwritten limits would be unwise and not helpful.
Threads can be locked by their owners (those that started them), as well as Toady (and any others given such powers, per sub-forum or site-wide). Some are locked after going beyond the intent of their OPs.
But the main problem here, I think, is that Israel vs Gaza is such a much more complicated mess of extreme viewpoints, from those not involved (I'm not aware of anyone directly involved, of either side, so it's distant opinionating mostly). Ukraine vs Russia might still have extreme viewpoints around the wider internet, but we don't really have anyone on the Russian side (we have actual Russians, here, but not ones subscribing to the Kremlin's position on all this) and it's less messy and (IMO!) more black and white anyway, at least at the moment. Maybe a bit of an echo-chamber, but a realistically-slanted one and better than a gladiatorial arena of diametrically opposed (and additionally perpendicularly placed!) opinions being batted back and forth in a manner that generates unwanted heat.
