“experts say”
LOL, oh ok, there are “official experts” in this area.
Good grief...
Yeah, "official experts" are there to say the opposite of what every human being knows from babyhood.
If all they did was say what everyone knows, they wouldn't sound like "experts," and no one would care what they said or pay attention to them.
The official experts run the sex change surgery centers.
Of course they’re vested in promoting this bullshit.
