Yeah but that still falls into the problem that there also was with the movie Bright (although Bright was much worse), where the basic idea was these different groups are taken to represent different races in real life (prooooobably ok so far) and there are legitimate differences between the races to establish reasons why people discriminate against them (this is a problem). So zootopia it was predator and prey groups, which there is a clear reason the audience instantly understood for prey to be afraid of predators or prey to be seen as likely to be less good at violent jobs than predators. But in real life between different groups of people there aren't actual differences that justify people being racist initially, racism is a system that has been constructed to maintain power over other people. So in zootopia its like, we have to learn that these ideas are not true and predators can be gentle and prey can be violent/evil, but it's kinda based on something real. If you carry that message into real life, you get "yes some people because of their race might be scarier and more dangerous because of stuff they can't help, but they can control themselves and be good people so we shouldn't stereotype" which is hella dicey and not based on actual differences between people. And people actually think like this? Like people talk about black men being more inherently violent or strong or aggressive, which isn't true, and then it's like, "well that's where racism comes from, some people just seem more violent so we decided to be racist, but if we just unlearn that it'll be solved", when racism as an institution is much harder to dismantle because its how people maintain power over others.
Anyway that was a really fragmented explication, but yeah zootopia is a fun movie but that underlying idea is kind of incideous, even if I don't think it was intentional on the creators part.
If you wanna hear someone talk better about this than me using Bright as an example (which is way less subtle than zootopia) it's talked about in this video, although it isn't the main theme:
