It came to me reading about Trying to Understand the hate. Many assumed the OP was doing the same-old same-old: "you guys are meanies, why can't you just be kind, there is so much transphobia here!" and it turned out the OP soon admitted there were things they had not considered. The lovely vixens of MN set about explaining their points very eloquently, as they so often do, and it was (is) a very informative thread.
And it is a work of wonder to watch when the world unfolds in this way, and the many lurkers following the thread will also learn the nuances of suicide stats, safe spaces, threats to women, etc. at the same time. I have learned so much from these threads that explore the details of the issues, and followed up ideas by researching them later on my own. All good.
The trouble is the bad faith posters. When mumsnetters are faced with someone trying to wind them up it is often hard not to "feed the trolls" and post on the thread. Many times the threads and their arguments go round and round. The trolls love this of course. If we had a FAQ we might be able to direct them to "see FAQ no. 47", say. This does mean that goady questions would have to be included, but the answers should be very straightforward, respectful, and the best answer with the information we have at the moment.
For instance:
What are the suicide stats for transwomen in the UK?
What is the "cotton ceiling"?
When trans people pass, would you really want the trans women in men's bathroom and the transmen in the womens?
And some topical ones, for instance (sorry Kelcat9494 for using your question, slightly altered, but it does stand as an example of the type of question we see quite often):
JKRowling said only women have periods, this isn't true though is it? Some biological women aren't able to have periods or carry a pregnancy so if we don't see that as a problem then why is trans-men having a period a problem and trans women not having one an issue?
The answer would include the failure in logic and also explain issues around transwomen erasing women's ability to describe their biological functions which is why "transwomen not having one is an issue".
Just a thought. And no, I don't volunteer to write the FAQ!
