Social justice warriors flipped out at feminist YouTuber Laci Green on Saturday after she said the terms “male” and “female” refer to biological sexes.

Last week, Teen Vogue published a visually explicit and kinda gross article about a certain sex act, which included diagrams of the female and male reproductive anatomy. The diagrams described female anatomy as the anatomy of a “non-prostate owner,” and described male anatomy as that which belongs to a “prostate owner” so as to avoid using the terms “male” and “female.”

But Green pointed out that these descriptions are insane, as the word female literally describes someone who was born with a female reproductive system.

lolwut? according to vogue, females are now “non-prostate owners” pic.twitter.com/aGSNKG6wOQ— Laci Green (@gogreen18) July 9, 2017

fyi this is what i’m talking about when i say i can’t even use *basic biology* terms in sex ed anymore. “female” = not inclusive (??)— Laci Green (@gogreen18) July 9, 2017

“female” and “male” are not identities or genders. they are biological sexes and refer to someone’s literal body parts (for reproduction).— Laci Green (@gogreen18) July 9, 2017

These correct statements about human biology were apparently too triggering for social justice warriors to handle, because they raked her over the coals.

Someone tried to tell Green she’s wrong, saying that a post-operative “trans woman” — that is, a man who undergoes surgery to appear female — runs the risk of developing prostate cancer. But this weird statement only proves Green’s point that those who are biologically male can’t magically become female, even if they like to call themselves that or have their bodies rearranged with plastic surgery.

huh? this is a contradiction. biological sex is the reason a trans woman still has prostate cancer risks post op. — Laci Green (@gogreen18) July 9, 2017

Another asked Green where she got her information about the sexes and their respective biology, to which she responded: “an elementary level biology book.”

an elementary level biology book. — Laci Green (@gogreen18) July 9, 2017

Some resorted to calling her a “TERF,” or Trans-Exclusionary Radical Feminist.

Laci Green: "Sex and gender are not the same thing. Sex refers to biological…"

laci green, crawling out of your browsing history from 2011 to tell you about how TERFs were right all along pic.twitter.com/DANt2xZYP3 — o shit waddup (@wrenwhite_) July 9, 2017

Hey pals, I've noticed that quite a few of you still follow Laci Green so I'm letting you know that Laci Green is a transphobe x — ✨CorbynStanAccount✨ (@HelloPoli) July 9, 2017

To be clear, Green buys into the whole “gender is a social construct and is not the same as one’s biological sex” thing (which this writer thinks is hogwash), and made that very clear in her responses to critics on Saturday.

k. female = vaginas, uteruses, boobs, higher estrogen, less body hair. literally just basic biological facts. doesn't determine gender. bye. — Laci Green (@gogreen18) July 9, 2017

sure, there is no "purity". overcomplicating w/o necessity. reproductive hardware to get pregnant = basically female. if no, basically male. — Laci Green (@gogreen18) July 9, 2017

But that’s apparently not enough for progressives, who say everyone must ignore physical and biological realities in order to appease those pushing the transgender agenda.

This isn’t’ the first time Green has been blackballed by liberals for saying things they don’t agree with. Last week Green was added to a list of commonly blocked Twitter accounts that sensitive liberal use to purge their feeds of thoughts that may contradict their own. It was also revealed that she was dating an anti-PC YouTuber, Chris Ray Gun, for which many have criticized her.
