It's very demonstrably not even the case in most cases we deal with that everyone getting something acceptable is more fair than some getting their favorite. Maybe in a hyper-egalitarian situation that is the case, but in most cases there are some who have more at stake and are more vulnerable. It's important to remember what it means for a situation to be fair, a situation that we would impartially approve of (say, by not knowing who we are in a situation and acting in our self-interest). In such a situation, you'd want those with the most at stake to get their way, even if they're the 49% and the rest aren't happy with it. If we don't accept that then it's really unclear why we anarchists give a shit about consensus.
In this case, everyone may find a particular choice acceptable, but find the overall decision-making situation unacceptable. Like, if you're disabled, and you rarely get to eat foods that you enjoy, and your friends invite you out, you may find certain restaurants acceptable because they at least have fries or a salad you can eat without throwing up but you'd love to go to one of two restaurants. Your friends eat out every other week and can eat pretty much anything, minestrone, rotini, a whole plant-based ice cream cake each, whatever. You may find those acceptable restaurants acceptable, but find it unacceptable that your needs and desires don't outweigh the others for this decision-making.
It's not fair. It's obviously not fair, even though everyone is getting the acceptable option. In this case, going where you want, even if the others would prefer not to go to those restaurants, is fair. And most group decision-making situations today are like this.
are the animals that totally have no way of communicating any of their thoughts or attitudes in this room with us right now
