I guess it depends on the person, but it would be to me if I had a mental illness. Kind of like calling a person in a wheelchair a "cripple." Word meanings change over time, and those words are now used more in a negative way than just to denote a specific bodily or mental ailment.

Yes it is. "Crazy" is an offensive word that people say when they don't understand something or don't know the correct words use. The word crazy marginalizes people with mental illness.
The mentally ill are treated in hospitals and clinics that specialize in mental illness. The term 'crazy' and 'crazy people' is a generic term that can mean anything wild, violent, oddball, enthusiastic, or strange. A crazy person doesn't equal a mentally ill person. The word 'crazy' can be a positive or a negative description. Examples: She wears such crazy clothes. He's just girl crazy. When I said that, she went crazy. He ran like crazy. That was a crazy thing to do. I think the word you seek is an asylum.
Your question is quite offensive to me.
They're crazy
My sister is so crazy 4 this guy!
he was crazy
No, it is a disparaging slang idiom meaning physically or mentally weak or effeminate. Not a cuss/curse(UK) word but equally offensive to some.
The multiple colors of paint splashed across the walls were colorful and crazy.
In the u.k the word "retarded" would be seen as quite offensive. We use terms such as "mental impairment/having a learning difficulty/cognitive disability". However, through different research, in response to your question, I have heard the term "mentally challenged" and "mentally retarded".
The word retarted means mentally slow and unable to learn as fast as others. However, it is often used to offend someone and call them stupid. Having a brother who is actually mentally retarted, hearing this word spoken out of place OS offensive to myself and others.
Using the word nutcase is not socially acceptable. You should use the word mentally ill to refer to someone who has issues with their mentality.
