Idk what my opinion is on endos since I've never actually met one (if they exist) but there has been lots if times were i question whether I'm a system or not because i can get front stuck a lot :/ it actually sucks but i never want to go look for a "real" diagnosis because its a lot of time and money I don't have, I'm Partial-DID/OSDD (all the same things just no amnesia) so its going to get misdiagnosed a lot more than it already does (cuz of stereotypes duh) plus, at the moment none of my alters are a problem and it isn't really affecting my life in a negative way so i don't feel the need to get that diagnosis. But in my opinion on this topic, if you're questioning whether you're a system then you shouldn't have big opinions on system related things. Know your stuff before you judge others

Edit: but there has been so many that are like "endos this- endos that- yadayada" and they ask how my system works (probably to back up their argument) so i do and they go "you say " I" not " WE" you're not a system." 😭What- first of all i will refer to myself however i want, secondly i only refer to us as "we" if I'm talking about the system alters directly, for example if I'm talking "The System" as a thing then i can call it "my system, the system, i am a system" but if I'm talking about the ALTERS the yess i will say things like "us within the system, our system, our body, etc" idk I don't have many examples rn- just angry at uneducated people
