Like I said before, you can ask for evidence all you like - a lot of it will already have been deleted and for the rest it will probably be refuted that it is actual evidence of transphobia.
The difficulty is, either way, mumsnet still has an image problem on trans issues- people can cry to the heavens that it's not justified - but that is what is out there, and that is what is thwarting commerical relationships. And the tone of threads is probably enough to set that.
Do you think other organisations are going to do a forensic analysis of the site to come to a judgement?
. They really can't be arsed. It's enough for them to know the perception bends that way and a cursory glance at the forums will probably reassure them of what those lobbying are saying.
There are too many personal attacks, too much reliance on dogma, too much derision, contempt, suppression and coordinated drowning out of differing views. Sum and substance of it: It just looks bad.
