In simple terms, it’s when somebody claims to be born a system or was formed without trauma, and is an umbrella term for all non-traumagenic plurality (from what I’ve heard, don’t take this as absolute fact). They are harmful to people with DID/OSDD, whether they realize it or not. However, there is a very low chance that someone claiming to be an endogenic has forgotten their actual trauma, although this is highly unlikely.
They get a lot of hate online, whether it’s because they’re seen as “stupid” or “idiots” or whatever. Though, this doesn’t make whatever actual problems they have any less important because there is a chance that it was a misdiagnosis or missed diagnosis, with an example being BPD, as BPD splitting is similar to DID/OSDD splitting.
Person 1: I’m an endogenic system
Person 2: GET OUT OF THIS COMMUNITY NOW, YOU IDIOT
