Yes, but you and the grandparent commenter seem to treat it as black and white -- either they are sane, or ALL logic has gone out the window. Many (most?) actual mentally ill are not like that (spoken from first and secondhand experience) -- SOME logic has gone out the window, and there is room to "negotiate" or "convince" in alternate ways. But that requires getting to know them, caring, spending enough time to earn some trust and understand more what kind of entreaty would most appeal to them. A good comparison is a young child (or an elderly person slowly getting senile)! They often believe silly things, but it's not all or nothing. It's possible to "reason" with them, but it takes more effort, time, and care, that's all.
