So is it basically saying that many people follow different types of utilitarianism (I'm assuming this means the "ambitious moralities"), but judging which one is better is quite neglible since all the types usually share important moral similarities (I'm assuming what this means "minimal morality")?

To be honest, the text of this article is extraordinarily long and hard to comprehend. Is there like a simplified version of this text that is in simpler English and is much shorter?

Hi, in the city I am presiding there are a lot of homeless people.

A lot of these people are near grocery stores. Considering meat is a high protein source, like if you buy turkey slices, I feel like that lasts (compared to buying something like tofu). So I was wondering whether its okay to buy meat to give it to a homeless person. This forum seems to think veganism is highly impactful so I don't know. 

Or perhaps, rather than donating meat, I could donate money to them? I don't know if that is good either because there isn't really much of a big difference if a homeless person buys meat vs I buy the meat for them.

Furthermore, there are some instances where some argue that homeless people would spend the money on drugs and alcohol. But when I'm not in a position to give food (because I don't have it with me currently), I donate like a dollar. Would this be considered good or bad?

But boycotts where you are trying to make a policy change require mass organization then?

So I shouldn't care too much about opening strangers water bottles and opening the cap or whatever and emptying its contents, kind of like what the article says. Interesting.

Could the same logic be applied elsewhere? 

E.g. boycotting Nestle results in reduced money for Nestle which causes Nestle to exploit people in Africa less?

Idk, red cross says check with a physician beforehand. Furthermore, the blood donation center I am currently going to frequently asks if I am taking those supplements before I donate. It seems like there must be something external that is relevant about those supplements - its not just another source of iron.

How is veganism effective then? Like blood/platelet/plasma donation is ineffective because there are already lots of blood donations out there, but somehow veganism if effective despite there being plenty of meat eaters out there?

Furthermore, earlier on regarding saving hospitals money, I have been thinking if that really saves any lives in a very indirect manner. For context, I live in the US in a for-profit healthcare system. Should I care about saving hospitals money? Who receives the benefit in this scenario? Maybe hospital has more money to save more people, or maybe the admins in charge gets a bigger payraise...

Then why does the Texas Water Quality Association say its a problem? Furthermore, technically its not removed from the water cycle permanently - but its removed for a really long time. Overall, small removals will snowball into large removals given infinite time...

Edit: Furthermore, this makes it sound like wasting water isn't that big of a problem. Is it the case that conserving water is effectively useless?

To be honest for some reason, there seems to be some wariness regarding iron supplementation (I am supposed to see a physician before doing this). I currently am not able to do that. Its just lots of people here seem to view blood/platelet/plasma donation as not effective altruism, but view veganism as effective altruism. So I was expecting responses to be more biased towards veganism than blood/platlet/plasma donation...
