What if someone wanted to change their looks via surgery to replica Bruce Jenner and even change their name the same? Let’s say he went around and made entertainment money off of it. Since Bruce has been Caitlyn’d can ‘she’ legally object? Now that would be some theatre of the absurd.
There was a science fiction story to that effect. One element included a person who had his appearance and his name changed to that of a popular fictional character, and then sued the fiction author because he considered the character’s behavior “slanderous” to his new identity. “I have never had sex with an alien!”
There are still a lot of people making money by impersonating Elvis, though I think his shelf-life is much longer than Jenner’s will be.
The next, ‘Freak of the Week’ will be along in about 15 minutes. ;)
