There are multiple stories about the protest. That, in turn, will animate both sides.
The Americans who lightly support Israel aren't bombing anything. They're the ones who get animated by giving the issue name recognition.
While 55+ is strongly pro-Israel, 35 to 54-year olds are moderately pro-Israel [1]. So sure, in 30 to 60 years we might see a demography-driven shift. (Gen Z isn't pro-Palestine as much as more evenly divided.)
One of the strategic mistake the American pro-Palestinian movement made from the beginning was deploying majoritarian tactics. Those don't work if you don't actually have a majority. (This protest is an example of it.) Instead, the movement should be deploying minority tactics in the way e.g. the gun lobby does.

Here is one a year later from the same publisher: https://news.gallup.com/poll/657404/less-half-sympathetic-to...
33% are sympathetic to Palestinians vs. 46% who are more sympathetic to Israel. Support for Israel is the lowest since they started measuring in 2001 and is showing a pretty rapid decline. Among democratic voters Palestine support is actually greater than support for Israel (59% vs 21%). Among the youngest age group (18-34 years old) support is 48% for Palestine vs 31% for Israel.
The takeaway isn’t just the shifting demography it is also a shift in support. More Americans are changing their opinion, away from Israel and towards Palestine. Especially among the Democratic voter base.
In Australia 60% of people view palestine favourably whereas only 39% view israel favourably (ADL 2024 Antisemitism survey)https://www.adl.org/adl-global-100-index-antisemitism
It’s very difficult to disentangle how much the effect is driven by Jewish and Israeli diasporas (and others’ proximities to them) [1] versus outright bias. An Australian paper isn’t going to be held to account the same way the Times will be, arguable from both sides, because the latter serves a larger and more-diverse audience.
