Fair criticism, and in regards to minerals especially, I totally failed to mention the need for herbivores to have access to literal rocks and dirt rich in different minerals that aren’t readily available in plant. In captivity, this takes the form of mineral blocks of course.
Many herbivores have a part of the digestive tract devoted to fermentation (or other microbe based processes) to break down cellulose. This involves a community of microorganisms that live in that part of the gut, and it is those microorganisms that break down the plant matter, producing nutrition for the animal via the products of their digestion, or by the animal breaking down the microorganisms themselves. Ruminants in particular like cows with their specialized multi-compartment stomach devote a lot of space to culturing this microbe colony, but rabbits and horses are hind gut fermenters so they have cecum for that. Rabbits also are coprophagic (eat poop), they digest some of their plant matter once, then eat the poop pellet and send it through again so it can be broken down even more.
But basically, with the microbes doing the work of digestion, it is more about what they can extract, and the herbivores just host them. We have a different community of microorganisms than them, and our digestive tract wouldn’t be able to support large numbers of those species.
Well fortunately on Lemmy people can create multiple versions of the same community to be ran in different manners. People can vote with subscribership. Beehaw is an example of a more heavily moderated instance that might align better with your goals and opinions about this. If the space you’re in takes a more laissez-faire approach to moderation, but that is the general desire of the community, it makes sense not to impose your desires on them if other more congruent options exist.
If you want to take up the time burden of moderating large communities for free you can contribute to the solution but it is a lot of work with no compensation, so there is a valid reason that throwing more moderation at the problem is much easier said than done
