I don't think this is the strongest case for abortion, taking the world view of the protesters as a given. If you presented this BOTEC to them, I think it's very likely that they would tell you that they care much more about humans than chickens.

I would guess that weird EA ideas that were appropriately caveated would do reasonably well here, and the main negative reaction is to weird ideas that are presented overconfidently? But this is just my impression of the Forum, not a result of looking over how various posts are done.

I do list this on my donations page, but I'm trying to be pretty conservative in what I count as my donations: only the actual money I actually donate. So I don't count it towards my 50% and put it in grey italics like my employer donation matches, donations in exchange for work, the PayPal 1% match, and other counterfactual money moved that I don't fully include.

I think it's fine (and probably good) if others are less strict about this, though!

Thanks!

I think it's some combination of temperament (I just really like writing!) and practice (I've been writing posts multiple times a week for over a decade)?

I think you're probably also only seeing my better posts, since I don't cross-post most things to the Forum?

Wow!

If you'd like me to review it for accuracy before you publish it I'd be happy to!

Sorry! I've edited my comment to make it clearer that I'm trying to say that suffering caused by eating meat is not the only factor you should weigh in estimating expected utility.

(For what it's worth I do still think it's likely that, taking these other benefits into account and assuming you think society is seriously undervaluing the moral worth of animals, veganism still doesn't make sense as a matter of maximizing utility.)

Therefore, veganism does not make sense for someone aiming to maximize their EU. ... The only other factor stopping me from eating meat was a deontological side-constraint.

It looks to me like you're not including some other pretty important ways veganism can increase expected utility beyond the direct impact of reducing the suffering caused by your diet. For example, it's a clear signal to other people that you think animals matter morally and are willing to make sacrifices for their benefit. And it helps build a norm of not harming animals for human benefit, reducing the risk of locking in speciesist values. I think there are many EAs who wouldn't make the sacrifice to be vegan in a hypothetical world where no one would ever know their dietary choices, but who think it's a very important thing to do in the world we do live in.
