>Do you think it's socially acceptable to ignore everything that doesn't affect you personally?

No one has the time to pay attention to every little injustice in the world. For all the people crying about Gaza, how many of them are dedicating as much energy to the wars in Sudan, Yemen, or Myanmar, or the abuses by Russian security services (like imprisoning a guy for holding up a blank card)? This isn't to say that we should just ignore Gaza or Ukraine or ICE in the US, but we need to make a choice: either we spend ALL our energy addressing every injustice in the world, until there is no more injustice left (and this means we need to stop everything else we're doing now, including keeping society running, making food, etc.), or we need to choose when and how much attention we'll devote to various issues.
