You still haven't answered the original question - what is so hard about referring to Chelsea Manning by her legal name?
And as far as India is concerned, transgenders who aren't transsexuals are legally recognized as a "3rd gender." They're safer in India than transsexuals in many parts of the US. And Iran, transsexuals, unlike gays, are accepted because Khomenei made it clear that transsexuals are their new sex, and must be treated as such. You don't go against a fatwa without consequences.
You don't know much about this, just stuff that's been debunked and your own prejudices. Cut the hand-waving and answer the question that started this - why can't you refer to transsexuals by their legal name? Did someone touch you where they shouldn't have when you were a child?
