But that doesn't help if you have a weird PTSD reaction to the idea of "questioning your own beliefs and then changing them" because you're afraid you'll Completely Lose It, or Wind Up A Completely Despicable Horrible Person, or Get Mobbed On The Internet And Have Your Life Ruined, or, or...
And that's dramatically easier to wind up with than you might expect from the term "PTSD". Surprise: everybody's got bad shit that's happened to 'em, that's life. Some of 'em lose it in rage and lash out. Some of 'em shut up entirely, dissociate hard... apoptosis, even, unfortunately. Sometimes literally, sometimes metaphysically- one's not much more sad than the other, but the literal apoptosis isn't reversible from the perspective of others.
I can type like this, show off Pure Unfiltered Self, and then switch to my work laptop and write up client reports. Can you? Why not? Anybody can write weird meaningless stream-of-consciousness stuff. Some people just don't want to. Most people just "don't want to".
