Lots of people like to say “I never support a genocide”, but they never asked the question, “would I turn a blind eye to a genocide?”
That’s basically what’s happening here. Lots of people not supporting the actual killing, but doing nothing to stop it, not even speaking up.
Until it’s at their door, until it is threatening them, a lot of people in this highly individualistic set of societies do not give a shit if a whole people gets erased from the face of the planet.
