Personally it impacted me in a way that I have lost faith in humanity. Everybody talks, but no body cares, no body takes serious actions. Kids, women, elderly, whole families are being killed for almost two years and no body gives a shit. Millions of people trapped in a land and moved from north to south from south to north like animals, have you seen videos of starving people running in masses to get food from aids…
My opinion is caring about the Palestinians is incredibly performative. People that claim to care about Palestinians care about 'the cause' but not the individuals themselves.
My main concern is how quickly what I would have considered Western value structures, democracy, press freedom, international law, reasonableness have evaporated and I now see the West, and the US in particular very differently.
Allowing one group, in fact enabling them in so many ways, of people who we have close affiliations with to kill, starve, displace and torture an entire population, no matter the reason, just makes me see the world in a very different way.
This centuries illegal wars had opened my eyes somewhat but even those I'm going back to and re-evaluating and seeing them and the current situation as frankly great evils.
I'm old enough to not really have to worry for myself, but selfishly it does make me very concerned for my children.
And yes I am more than concerned for the Palestinians, if that is the "cause" you are referring to.
