"when one group of people is claiming to be scared of the other"
The fact that this site even hosts that particular debate will never cease to rightfully upset some. For it to take place at all, it has to tolerate non-natal-females gaining entry to a female space ie Mumsnet/Feminism. Even if only 1/1000 women feel that this is intolerable, then it is intolerable. Her rights are stepped on in favour of Trans rights. Trans. is not itself a Feminist problem.
But seeing as I'm here now anyway, has anyone suggested some sort of "code-of-conduct" for non-females to adhere to when navigating around? It may clarify an uneasy relationship without feeling like a compromise.
