People act the way they think people act

Most people act the way they think people act. When people talk about what people are like, assume they’re including themselves.

For instance:

If a boss says that all bosses exploit employees, they’re likely to be terrible to work for.

If a man says that all men are rapists, misogynists, or abusers, he’s likely not a very safe person to be alone with.

If someone says that all marginalized people need to lash out at privileged people, it’s likely that they’ll eventually consider you privileged and lash out at you.

There are any number of instances of this. People tend to act the way they think people act. When people tell you how people act, or how people in a group they’re part of act, err on the side of assuming that they may act that way too.
