It's not the angry part that's your true colors, it was all the slurs you yelled while you were angry.

While you're right in pointing out that what people do when angry is most often closest to their "true colors", it's also undeniable that many racists happily assume the angry state of "undesirables" is their "true" form... because they're racist assholes and cannot imagine certain other races/minorities as normally nice/kind.
Probably because they antagonize them and then go, "see you are capable of being angry, and I only see you all being angry (because I'm an antagonist) so that justifies my ignorant, self-produced belief!"
I think that diagnosis does come from people who go around being miserable all day and are conditioned to "fake it" in front of everyone and don't see the obvious connection in those behaviors.
So much of the world is just undiagnosed personality disorders who refuse to get therapy.
There are people who are seemingly almost always happy, constantly lead some social activities, energetic. I can't help it. It instantly activates some defense mechanism. They seem so out of place.
Being angry, pissi/whiny, lazy slob seems much more normal state, it's like that is the normal state of a human and the happy ones are an anomaly or yes trying to sell me something or manipulate to get something out of me.
