On this thread there have been a number of posts from MNHQ, one of which contains this statement. https://www.mumsnet.com/talk/womens_rights/5342469-just-checking-since-the-sc-there-is-no-such-thing-as-misgendering-on-mumsnet-or-is-there
It is only a 2 page thread, and the first post (in blue on my screen) is at the end of the 1st page with more on page 2.
Just thought some might like to suggest who has been lost and missed because of an earlier strict regime!
