I think neither of these is true. a) is IMHO false unless you care to a similar extent about all the other atrocities happening even as we speak - most of which elicit a response of "oh that's sad but what will you do". The reason why people care about this conflict (myself included) is because it has become a proxy conflict that is really about other things.
b) is IMHO false because the real action one should take if one cares about this is first and foremost contact anyone you know who is affected by this conflict - even if indirectly, say, by antisemitism or islamophobia - ask them how they're doing and express your support (not necessarily for their positions but for their plight).
I really don't understand what good it does anybody to engage in debate about a topic that is so politically charged and where almost everyone has only half-knowledge (or less).
I did my best to moderate this thread, to the point of overload, and yes there was a lot of flamewar and guidelines-breakage that I simply couldn't get to.
IMO what we need to do is find at least a drop of (let's call it) heart in ourselves not only for the ones we identify with, but also for the ones we don't identify with. That's how we can start being human about this. If even a tiny amount of that is possible, and of course it is, then we owe it to ourselves to try.
