Friend of that friend:

Many homeless people are mentally ill and some even prefer to be homeless. ... I read the memorie of a girl who was raised homeless and her parents were nuts. ... It's funny, in the end of the book "The Glass Castle" the homeless girl was able to get herself to college and had to listen to a lecture from a professor going on about the plight of the homeless and she challenged him that he was wrong. This woman was raised homeless, in the end she found out that her mother had about $1 million in property. Not all homeless are like this, but a good percentage are mentally unstable and some prefer life on the streets.

Other friend of that friend:

I once heard that nearly half of all homeless people are mentally ill. If stupid people hadn't called for the defunding of mental hospitals based on what they saw in the movies, this wouldn't be happening.

Me:

It is very much better to be homeless than to be in Mental Hospital.

The so called Statistics saying that "half the homeless are mentally ill" are made up by people observing the homeless with training acquired from the pseudo-science of psychiatry.

That means that such statistics are worthless.

What could be informative is trying to find out how many homeless are kept on the street by people CONSIDERING them as mentally ill and who have sufficient "credibility" with people to make those kinds of statistics.

I am now unfriending [that friend], not for being friends with Pat, but for being friends with other people who like to consider homeless people as mentally ill.
