It's just so offensive.
It would be so deeply, obviously offensive if a white person claimed to be in 'black mode' from time to time.
It would be clearly deeply suspicious if a grown up man proclaimed himself to be in 'child mode' and demanded unfettered access to children's spaces (but I invite anyone unfamiliar with this concept to perform a Google search on Stefonknee Wolscht).
But when a man, who has always described himself as a 'man in a dress', decides to flip back and forth in 'girl mode', as if being female is a costume one can put on and discard at will, that is apparently perfectly acceptable.
Izzard has spoken before in interviews how he chased some teenage girls out of some women's toilets when they questioned his presence in there.
Who has the right to be in the ladies loos? Some teenage girls? Or Eddie in a dress and some lipstick?
Ten years ago I really liked and admired Izzard. Not anymore.
