Hey Kpobo! Please link us to the research that states that. Just as a heads up, if you haven't interacted with a transgender person on a day to day basis, researched the topic extensively, or listened with an open mind when others try to educate you, you really aren't qualified to be commenting on this topic. Please get back to us with proof of that statement and once your knowledge on the topic has increased, and then we'll chat. Thanks!!
