How prejudice can be manifested?

Answer 1

On one account, prejudice involves failing to take into proper account a person's (or, more generally, an agent's) interests simply because of some arbitrary fact or feature of that person (or agent). For instance, a racist might discount the interests of people who belong to a race that she dislikes. A sexist might discount the interests of people of the 'wrong' gender. And so on. People discriminate against others on the basis of race, sex, class, religion (or lack thereof), looks, sexual orientation, and more.

Prejudice stains our relationships with animals, too. Just as many people are racist or sexist, so too are many people "specialist": these people fail to take into proper account the interests of other beings simply on account of their species. They say, for instance, that animal suffering doesn't matter because it's *animal* suffering rather than human suffering. Without further explanation, this argument is no better, no more convincing, than more familiar modes of discrimination like sexism or racism.

Answer 2

Prejudice can be manifested through discriminatory behavior, such as stereotyping, scapegoating, or withholding opportunities based on preconceived notions about a person or group. It can also be seen in interpersonal interactions, such as biased language, microaggressions, or exclusionary practices. Prejudice can occur at individual, institutional, or societal levels.
