Oh this is brilliant. Thanks for sharing. It's great to see a tiny fraction of what's being said in other online spaces by people who also live in the real world. 
Some of the responses made me laugh out loud. Shame we wouldn't be allowed to repost some of them here. I mean Mumsnet is such a hotbed of transphobia and hostility towards trans people... That's why we wouldn't be allowed to say the sort of things being said elsewhere.
Hey keyboard warriors! Don't be shy, I know you're lurking in the background. WAVES
I take it all of you will be rushing over to TheColi and NeoGaf to wag your fingers at the men there and tell them off for their words of literal violence and how they need to do better, right? Right? Let us know how your exploits as brave keyboard warriors go in 'educating' men about their 'transphobia'. You could even post on Twitter about how disappointed you are in them.
