This is evident when the citizens of Zootopia rapidly blame the predators of their society for the outbursts of a few on what must be "them being born that way" instead of looking for and identifying what external factors could be causing it. this is essentially what happens in our society when people may blame the ethnicity or color of a person for their actions, rather than looking at why they did something, or whatever outside factors motivated the person in question to act a certain way.
the outside factor in our society being what is usually considered an environmental factor such as education of income. this is perfectly represented by having an actual part of the Zootopia environment part of whats causing these tensions.
The second act of this analysis is to also shed light on the issue that stereotyping has on the perception of ones self, and also the perception others may have of the subject. By playing on the trickster character that foxes usually portray in folklore, the makers of Zootopia put Nick Wilde in the perfect position to show the issues of inter-sectional racism and prejudice. By being a predator in that specific time, he was already looked at negatively, but by also being a fox there is additional stress put upon him. to the point that he justifies his own behavior at certain times by saying "Its what foxes do" because of how warped his self-perception is due to the barrage of inter-sectional-racism he experienced as a child.
