What part of the world? Because remember algorithms and peoole curate their social media intake. I'm sure in the ME we know who is winning. But I can say the same about Evangelicals in The USA. And yes that includes a lot of Democrats.The Palestinians will, on account of their suffering being very real and right there in front of everybody to see.
But again, the audience also matters. Overall, I'd say the Palestinians will.
I think a lot of people, beyond a sentiment of not wanting to see people dead, have a more "a pox on both houses" attitude about Gaza at this point, and really won't care much if it all just goes away.
