Upvoted not for agreement*, but for expressing well what seems like a common enough sentiment, in a way that's efficient and useful.

*Agreement, given my current state of mind, would be odd because I, well, identify with effective altruism in ways you don't. I don't disagree with you, though, because I don't disbelieve your stated preferences and values. I don't think less of someone who isn't "on board" with effective altruism, either. Agree/Disagree seems like an error; we just perceive and act on what we value differently.
