I try not to make fun of these types of people because you never know which ones are real and which are Poe's Law, I don't want to perpetuate that shit
I'm in the same boat, kinda. I understand there is a breadth of human experience, and I also understand that brain chemistry can make you genuinely invested in some daft shit. However, this contrived pluralgang shit is quite clearly contrived shit. Sometimes you need people to cut through the fog and say 'you're not half cheese sandwich and half celestial dragon headmate, you're traumatised and running away from your problems into a fantasy land that nobody else respects, they're just humouring you'.
Certainly if it was my kid I'd be speaking much more frankly than is 'internet acceptable'. Wouldn't be my kid though, and that brings me back to 'maybe sometimes harsh realities should be spoken'.
