Bill Nye The Unqualified Science Guy has a new, unwatchable series on Netflix inaptly titled Bill Nye Saves The World (spoiler alert: he doesn’t). In that series, Nye has promulgated unscientific notions about sexual orientation (everybody is bisexual, including ice cream):

He has promoted bizarre ideas about killing the children of those who live in the first world:

And, of course, he introduced all of us to our sex junk with the help of My Crazy Ex-Girlfriend’s Rachel Bloom:

One of his craziest causes, however, is the notion that gender is utterly malleable (the left regularly conflates gender with sex, and Bill Nye is no exception). This, of course, ignores biology, which says that sex is not malleable.

And Bill Nye used to know that.

Here he is in 1996 rightly explaining the biology of sex:

In this segment, a girl explains that “inside each of our cells are these things called chromosomes, and they control whether we become a boy or a girl. Your mom has two X chromosomes in all of her cells, and your dad has one X and one Y chromosome in each of his cells…X you’re a girl, Y you’re a boy.”

SCIENCE!

But teaching children science is ever so much more scientific than teaching idiot leftists science. Here’s Bill Nye skewing the science to suggest that sex is malleable:

This rather wonderful tweet demonstrates that while there are variant genotypes, the notion that they are anything but wild outliers or that variant genotypes somehow explain transgenderism is nuts.

But Bill Nye isn’t about science anymore. He’s about indoctrination into leftist groupthink.
