You should take your own advice.

Again most people in this thread have said: describing behaviours as crazy isn't the problem. Describing people as crazy is.

It makes you sound stupid. It makes you sound like that embarrassing racist grandparent.

It creates a culture where it's acceptable to shoot and kill people with mental illness (about half the people killed by US police each year have mental illness). It creates a culture where people with mental illness are discriminated against in the workplace. It makes it harder for people with mental illness to seek treatment.

Stigma kills people.
