Rachel, did you read the beginning, where Promethea explained the outright rejection from her parents when she thought she was intergendered (nice word)?

If you reread what she wrote about coming out, nowhere did she say that she was starting a discussion in order to sever relations, but - in my opinion quite rightly - she did say that if her parents show the same level of hostility and rejection to the news of her transition then she will cut the ties.

Promethea, I would like to suggest that if you are forced to cut the ties with your parents, just leave a channel of communication open in case they later change their mind and want to apologise.
