Unless you’re uncomfortable with them having number names continue let them using their number name. It’s not disrespectful and they’re not exclusive. It’s not like a close practice. How many singlets do you know with the name zero, I know, at least three. Unlike close practises number names are just something that happens. There’s lots of reasons for them to exist, yes RAMCOA is one but there is many more. Our Ramcoa support group had talked about this and basically everybody there and a lot of other people I’ve talk to have a greed that it’s not exclusive, so unless you’re uncomfortable continue using them. If people are giving you shit about this redirect them to like people like me or switch case. 
i have a bit of a question regarding using number names as a non-RAMCOA survivor.
we have alters and many fragments who have numbers for/instead of names. we’ve been questioning being RAMCOA survivors for a while, but ultimately decided to simply drop it as it was damaging us and our mental health more than anything, and it really isn’t something we should’ve been looking into at all in the first place without the help of a therapist. i personally (jay) don’t believe we’re a RAMCOA survivor, but many others in the system genuinely do and it’s not exactly a debate we can settle easily.
my question is, what do we do about these alters and fragments? we don’t actually know whether we’re a survivor or not. do we just not let them front, or force them to pick names (something we have tried, but made them extremely upset/uncomfortable because according to them they had names, which were their numbers)? none of them front very often anyways, but right now anytime any of them have fronted they’ve essentially just been told they can’t talk anywhere publicly. we’re really stuck on what to do. we know it’s disrespectful, but we also don’t have any idea for sure if we can use them or not, and like i said we’ve completely dropped trying to figure it out because of how both damaging and potentially dangerous it was. what do we do?
