Why do Donald Trump fans ignore the facts?

I have heard some people say Trump Derangement syndrome is a mental illness.

The truth is that it is not a mental illness. The American Psychological Association (APA) does not recognize "Trump Derangement Syndrome" (TDS) as a mental illness.

Trump Derangement syndrome is not included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
