Are EA billionaire philanthropists actually effective in their 'altruism'? (spoilers: no)
(bobjacobs.substack.com)
I have no idea what Peter Singer has to say about Gaza. I haven't heard anything decisive about what the most effective way to help stop the genocide is, I don't think there is much evidence on the matter right now. Based on EA I'd say do as much as you can, but don't neglect the possibly more effective causes like malaria nets and direct giving in the meantime.
Is your argument that Singer's philosophical arguments are fallacious because he hasn't delivered a guide to how to help the Palestinians? Because I don't think that works out.
If your argument is that he himself is a poor philosopher or activist for that reason, then sure, I have nothing against that.
