Mckenna is a stupid first name
Just stating the obvious.
Her parents must be really stupid.
Why do you think it is her real name? Did you also think that Natalie Portman is a real name?
It is entirely possible that she has a stage name to protect herself from predators like you.
It is a surname and not a first name. Her parents were at least very confused when they named her.
