It's not a strawman, I linked to an actual website. No, those people don't call themselves Effective Altruists, but they are engaged in altruism and are trying to be effective. EA is an outcome, not a process, and the EA movement has no patent on it. Yes, it's a weakman, in that I deliberately chose an obviously ineffective charity. But my opinion of the rest of the EA movement is not much higher. The comparison is neither bed nets nor deworming - according to GiveWell's top ranked charity, it's sending money unmonitored, and hoping against 60 years of experience that this actually improves things rather than just being a leaky bucket.
