I just googled her and she is a lot prettier than most transgender people I've seen who tend to still look masculine. She looks a bit like Rita Simons. In a way I can understand if she doesn't want to discuss her past because she might want to start a new life and confine her time as a man to history.
When she was a man it was probably out of jealousy and envy that she was mean to other women. A bit like that boy at school who is mean to all the girlies and pulls their hair because he secretly fancies them or wants to wear their clothes.
