• I actually used that example because some old guy at a thrift store said it to me. There are actually videos of people comparing unflattering photos of celebrities saying they have an Adam’s apple, or “too broad of shoulders to be a woman”. I didn’t believe it either, but it was a big thing in small circles called transvestigation. I don’t know if it’s still being spread anymore though.

      • It’s not so weird, it’s just that right-wingers have no imagination, and so many of their smears are of the I-know-you-are-but-what-am-I variety. (ETA: See also, the “Joe Biden has dementia” thing.) The “Michelle Obama is a man” thing came about because a lot of people used to joke that Ann Coulter is a trans-woman because of her prominent Adam’s apple. (Which she really does have.)
