This issues are hard. Tend to lead heated argumentation.

Yes, that's for sure.

I can't give a thoughtful advice but just to share my most sincere feeling toward this particular issue based on very personal experience. The way I have known is to elaborate, with the tools given by Buddha, my sufferings. Become aware of the amount of pain that has been kept since the event (atrocity) happend. Recognize it. Trying to stop nourishing it and eventualy, at its proper time, letting it go. It will never be an easy practice. It will take a huge amount of time and patient practice. Hope this do not harm sensible feelings Lazy, knowing that this has relation with cherished friends of yours. Actually that is a very thoughtful answer, Kaarine! Thank you.

I guess the question mark for me has to do with the sphere of moral/political/social action. It can be possible to confuse equanimity with indifference.

Wonder if the best response to give my friend (this is a purely hypothetical conversation) might be: "Buddhism does contain moral teachings and certainly doesn't constrain one from political or social action, but these aren't ultimately the purpose of the dhamma. The dhamma is more concerned with getting to the root of existential suffering, and with addressing it via inner transformation."

I know that sounds a little new-agey, but I would be trying to present it to a non-Buddhist and thus would need more generic terminology.
