> It's so odd how angry people get when someone tries to help others.
That's an odd description, given that the anger is because "effective altruism" is seen as neither effective at helping others nor honest about altruistic motives.
Despite manifold evidence that they are. See the sbf case. They get implicated for being recipients of donations from a fraudster. That's not a serious demonstration that they aren't altruistic and don't care about helping others.
