if this person has a "female identity" to some extent would this not by definition make them genderqueer or genderfluid to some degree and not a cross dresser? I have no issue with saying that the cause of this genderfluid people and TS would definitely be linked somehow because you are talking about identity issues. These people as well would suffer from some level of GD..
But for someone that identifies as 100% male but enjoys cross dressing for what ever reason, I do not believe that they are the same as TS's. If it was you would see the conversations between the two groups be more similar in nature and not focused on the superficial aspect of feminity
