By analogy, if a Catholic Church created a charity for curing malaria, and I donated money to it, that wouldn't make me Catholic. But still the existence of the charity, especially if people donated over a billion dollars to it, would be a credible argument against people saying "Catholics do nothing about curing malaria". Does that make sense?
How much more do they need to give before you will change your mind about whether “EA's actually want to do something about malaria”?
