IN answer to the first part - well I have and it has been a very uncomfortable time which has made me re think my position entirely. For the second part - let me reverse it. a woman cannot become a man ( any more than a man can become a woman). This is the basic lie. As for children being taught this. Well whatever floats your boat I suppose and I am happy for other teachers to teach it to children - so long as you don't teach it to my children.
