One of the big problems here is those of us who were born female and are quite happy to live as female, are expected to accept those who identify as female as though they are one of us.....and they are not.
I watch a lot of the shopping channels on tv and recently, one of the guests was obviously male...about 6' tall, big hands, broad shoulders etc....but had a girls name and was dressed in womens clothes. It was quite obvious that the presenter , a woman, was very uncomfortable and didn't quite know how to inter-act with this person.
The first time I saw Lady Colin Campbell on tv, I was trying to figure out exactly what she/he is. The proportions of a man's body are different from a womans. They might kid themselves , but they don't fool us.
