This is low-hanging fruit for scientology because they actually paint it as scary.
Scientology’s “war on psychiatry” is an accurate description because it’s not that they do not believe in it - they believe its effects are evil. As in, yes, you should have to suffer with depression, and schizophrenia, and anxiety disorders. And then you treat it by joining their church where they basically institutionalize you the same way it was done prior to modern psychiatry.
