Bess Kalb, a writer for Jimmy Kimmel’s late night show, displayed shocking ignorance about the Constitution on Monday, and then claimed sexism when people corrected her.

In a now-deleted tweet, Kalb said, “Real quick seems worth clarifying the Second Amendment isn’t in the Constitution. It’s an amendment to the Constitution.”

Twitter user Jon Bender responded, explaining that the Second Amendment is considered to be in the “amended version” of the Constitution.

Well, it’s incorporated into the Constitution, right? The amended version. — Jon Bender (@oblivious_dude) October 9, 2017

Kalb apparently didn’t appreciate being corrected and accused Bender of sexism.

Congratulations to this man for “Well,”-ing me WITHIN 10 seconds. Thank you for explaining this, Jon. https://t.co/uvjkeE6tXE — Bess Kalb (@bessbell) October 9, 2017

In additional tweets, Kalb argued that she was pointing out that the Second Amendment proves the “elasticity” of the Constitution. However, she didn’t do herself any favors when she then confused the 13th and 19th Amendments.

“I was going to throw a 13th amendment joke her way but decided that she wouldn’t get it,” one Twitter user wrote, referencing the amendment that prohibited slavery.

Kalb insisted it was “mean irony” to suggest she “wouldn’t understand the amendment that gave women the right to vote.” Of course, the 19th Amendment was the one that gave women the right to vote, as Twitter helpfully pointed out for Kalb.

“I was going to tweet at her about the 13th amendment, but I doubt she’d get it.” “You SEXIST. I KNOW it gave women the right to vote.” pic.twitter.com/K9IytkAuBa — Alex Griswold (@HashtagGriswold) October 9, 2017
