Because US and European countries very directly supports Israel in this case. In the other cases you refer to they are conflicts independent of western countries or at least the western influences are more indirect.

Our tax money is funding these atrocities. I felt the same way about the genocide in Yemen.

>Around the world, countless marginalized groups face equally dire or even worse conditions and would welcome similar support from these people

I don't think this is true. The majority of people dying of or suffering from starvation on earth right now are in Gaza.

>Yet, these so-called human rights advocates remain willfully ignorant of anyone or anything happening outside of the US and the Israel/Palestine conlflict.

You have blinders on if you think this is the case.

>Given this, how can anyone take these protesters seriously when they exhibit a groupthink mentality, lacking self-awareness or critical thinking, and behaving more like zombies than independent thinkers?

I'd rather you didn't take us seriously if you're not going to fully understand our goals or reasons for our beliefs.

Yeah, by comparison the total coverage of the ongoing devastating civil wars in Sudan, Yemen, Myanmar and Haiti is miniscule.

I guess to play devil's advocate, the US is much more involved in Palestine via its essentially unconditional military support for Israel, so it makes sense for the American left to make noise because in theory they could influence things.

Might be because we're funding this genocide ourselves...

This is textbook whataboutism. I live in the UK. I'm outraged by how much time/money is spent on Israel and Ukraine issues than our own. Similar to yourself, I have to wonder why UK govt chose to help one side with weapons in these specific conflicts. The difference here is of course, protestors are there on their own free will (for the most part, I guess?), whilst I don't have a say in how my tax money is being used.

I mean if anyone is yo blame for the Israel situation it's the UK.

I mean, yes. I can understand why protests happen, because our own govt is not currently acting in our interests.
