No I don't know anyone like this, it's very rare where I live. Transgenders have actual gender dysphoria while transtrenders pretend it to
have special privileges or to feel special, or so I have been told.
In answer to your question about transtrenders the answer is they should be left alone as long as they don't violate the rights of others. No, they should not be shamed or harassed. But if you are talking about who is truly transgendered, to me someone who is genuinely transgendered is someone who has been diagnosed as intersex and rated on the Prader Scale or Quigley Scale by an MD who is qualified in this area.
