I read MacAskill's What We Owe The Future - it's a great book, and a compelling argument. I recommend you read it.

What I suspect might be happening is that "do gooders" (as research has shown) are often attacked by others because those that do good are a "threat" to the status quo. Rather than living your life as you do, when you encounter a vegetarian, you are reminded that your meat consumption causes suffering in animals. When you encounter an EA (Effective Altruist) giving 10% of their income to charity, you are reminded about how you too could do the same but are choosing not to. So for many people, it is easier to find some shred of hypocrisy or fault in those doing the good and thus have the clean conscience to ignore the good aims.
