I'm not sure why you think it is offensive or erases anyone's identity. I don't object to it and have never heard anyone with DID object. For the record: my alter personalities don't object to the word 'everyone' either. In fact, it's useful because if there is something important you can ask 'everyone' or 'everyone inside' to listen which is much easier than asking everyone by name. And not everyone has a name or is willing to tell you what their name is or anything else about themselves. We DO strongly object to having people without dissocative identity disorder tell others what our views are. We exist and can speak for ourselves. DanBC - You don't say where you 0.1% figure comes from but 1 in 1,000 is not considered 'rare'. In the US alone that comes to a rather large number. The actual rate is between 1% and 3% - and varies depending on location, with the US having around 1% of people with dissociative identity disorder - for example compared to 0.7% with schizophrenia (source: DSM-5, 2013). Dissociative identity disorder is very often hidden, does not present in a way that people would especially recognize, and is a hidden disorder (like all the dissociative disorders). Stranger in the Mirror: Dissociation - The Hidden Epidemic is one of the better known books about it. Also the name of a website for the book. Tumblr is not a great place to get information about dissociative identity disorder because many people there claim to be 'multiple' or a 'multiple system' but actually state they don't have dissociative identity disorder, and don't experience amnesia, dissociation, or the effects of trauma which is the cause of it.
This is a useful blog addressing myths and facts with dissociative identity disorder. You' ll find good information on webmd, the merckx manuals, NAMI and pretty much anywhere with professionally reviewed articles about mental health. Healthy Place has a useful blog on myths too.
