I can't comment on the original poster's motivations, but I do know that some agencies (mine, for instance) will not release any information until the adoptee is 18, and then the adoptee perself has to request the information.

My hit on the comment was that she was saying that a person on a newsgroup could choose *not* to publicly identify as a member of a visually identifiable minority which is subject to oppression, and therefore spend some time not having to have such oppression directed at perself as an individual (although obviously such a person would still be subject to "ist" postings which aim at the oppressed group in general).

The person who called perself a dom, but then breached a safeword or did something similarly non-consensual.
