Come on, guys, really? You think Melinda is a man? Do you think it would be easy to hide a fact like that?
Well, Michael σbαmα didn't hide it well enough.
Joan Rivers blurted out (a couple weeks before she died during a routine endoscopy) that "we all know" that "Michelle is a tranny".
She did not look like she was joking.
People have done analyses of various tell-tale signs like the lengths of the index vs. ring fingers. In nearly all males, the ring finger is longer than the index finger, and vice versa for all females.
So if they could hide it for a high-profile figure like Michelle, the First Gentleman, then they could hide it for Manlinda Gates as well.
