Bit of a tangent, and I know the reasons, but I find it confusing that so many Arab countries have similar flags.
The difference in coverage of and interest in this conflict and others in the region is also startling. Apparently some lives are worth more than others.
You certainly don't hear much about the genocides committed in Sudan, often with the help of other Arab countries. IRC the RSF now fighting the government in Sudan, also fought in Yemen and Libya, for example. I assume they also have ties to Russia/Wagner or that they've been meddling in this war too.
People who are on 'team' Palestine, often unquestioningly parrot Russian (and Chinese) disinformation, because they're under the mistaken impression that their enemy's enemy is their friend. Russia has been a longstanding supporter of the Palestinian cause and an ally of Syrian and Iran, dating back to Soviet times. The Arab world often ignores how Russia and China treats Muslims, because it's politically inconvenient.
Some Muslim lives are clearly worth more than others. Take China. The UN is on record as saying what happened to the Uyghurs may amount to crimes against humanity. An estimated 16000 mosques have been demolished. A million Muslims in camps. Forced sterilisation. Medical experiments. Systemic rape. But you're very unlikely to see large scale protests to oppose that.
The left and Arab world doesn't care that much, in part because they've bought the Russian/Chinese line hook, line and sinker. Partly because west bad, so China/Russia good. Once you realise how selective the outrage is, it's also hard not to be cynical about the motives of some of those protesting.
Do they actually care? Are they protesting because they're angry that people are suffering? Or are they protesting because it's politically convenient and fashionable?
Obviously, what's happening in Gaza should be condemned. But it'd be nice if people came to the conclusion that war crimes are always bad, even when the guys doing it are on 'your team' and not look the other way.
