> A lot of my peers have been incredibly active on social media the last couple years supporting Palestinians.

So it took from 1947 (if not longer) to 2023 to have this population become aware of the problem. Still up until a few months ago, at least here in France, it was very unwelcome (and even politically persecuted, via house searches and terrorism charges) to even mention the idea of a genocide in Palestine.

I remember over a decade ago quoting israeli settlers, newspapers and politicians arguing a genocide was ongoing. But at the time, calling it a genocide here in France placed you in the loony bin in the eyes of most people. Given some time, the iranian revolution of 2025-2026 will be well-known.

Beyond the differences outlined by other commenters (that western governments don't support Iran, but do support Israel), there's this difference that few feel compelled to get over-active on this issue because every one already feels concerned: all the TVs are talking about it, and even the right-wingers are on board. Overall, everyone (apart from some islamists) are convinced that the Iranian government is criminal. Now what can we do?

Continue spreading awareness ; your peers may get on board! But better, get informed and involved. There may be, for example, a kurdish-iranian diaspora near you organizing solidarity protests and proposing courses to understand the politics of Iran, get versed in jineology, or understand the basic tenants of democratic confederalism. There's also other diaspora. I would just encourage you to be careful with the "Reza Pahlavi" crowd, who support a fascist regime change in Iran and would encourage just as much horrible crimes as those we witness today, if they weren't done in the name of islam.
