Do you really think that people can make up identities that aren't aspects of themselves? Humans are all capable of the whole range of human expression, we just get comfortable expressing certain parts of that. And certain other parts are really hard on other people, so we adjust our behaviour to match. (If we need other people in our lives, that is.) It's called "socialization", and usually happens during childhood.

I think that "rape" is a really harsh word to use here, and that "harrassment" would be more appropriate. Harrassment can reduce your trust in people without being the ultimate physical invasion.

I don't have Multiple Personality Disorder, but I do have Magical Personality Disorder..........

I have far too much ritual jewelry, far too many ritual items, know too many sets of divination to be able to keep them all straight, and have more magical names than the Great Goddess herself...
