A California man was arrested this week for allegedly threating to bomb Merriam-Webster's offices and kill its employees over the dictionary publisher's definitions for women, federal prosecutors said.

Hanson allegedly used the handle “@anonYmous” to post the a message on Oct. 2 on the comment section of Merriam-Webster's webpage for the definition of the word female stating that "Merriam-Webster now tells blatant lies and promotes anti-science propaganda," according to the U.S. Attorney's office.

"There is no such thing as 'gender identity.' The imbecile who wrote this entry should be hunted down and shot," he allegedly wrote in the comment section.

Hanson also allegedly wrote a message on the "Contact us" page stating the company's headquarters should be "shot up and bombed," federal prosecutors said.

"It would be poetic justice to have someone storm your offices and shoot up the place, leaving none of you commies alive,” he allegedly wrote.

The suspect allegedly sent related threats to other companies, non-profits and individuals including the American Civil Liberties Union, Amnesty International, Land O’ Lakes, Hasbro, Inc., IGN Entertainment, the president of the University of North Texas, two professors at Loyola Marymount University and a New York City rabbi, according to prosecutors.
