I doubt that performers who have had gender reassignment would publicly comment on whether or not the change has affected their hire-ability. What would be the point? If it has affected negatively they may think it just looks like they are playing a pity card which would draw unwanted attention. If it had not affected at all why tempt fate by drawing attention.

Sex change is not a problem or issue to my way of thinking. Just doesn't need to be thought about. Deal with the individual and their respective talent.

Now Species change as in Tone Deaf Leopard... that is something to talk about. Be afraid. Be very afraid.
