There have been a couple of threads lately where these terms are used quite readily to label people who display mentally ill or psychotic behaviour.
It makes me
and 
Why is it ok to do this? It's not seen as ok to label people in wheelchairs or with walking difficulties "cripple" any more, but I remember a time when it was accepted.
Why is it ok to dismiss mental illness with similarly bigotted labels?
Or AIBU?
