You see behaviour you dislike and don't understand and you can say either "they are unpleasant people" or "they are unpleasant people and they have a mental illness".
Probability tells us the first is more probable.
This is the conjunction fallacy, and you need to address it because stigmatising people with mental illness causes those people harm, and doesn't help address the actual problem (which is that some people are arseholes).
