Trump voters labeled 'fascists' by Scientific American editor-in-chief resigns.

The editor-in-chief of the oldest American magazine, Scientific American, resigned after labeling Trump supporters as "fascists."

Last week, Helmuth faced criticism for attacking supporters of President-elect Donald Trump after his victory over Vice President Kamala Harris, who was backed by the magazine.

On election day, Helmuth repeatedly attacked his supporters on Bluesky, calling Americans who voted for Trump "meanest, dumbest, most bigoted" and "f---ing fascists."

"I recall why I left Indiana, where I grew up, and appreciate those who remain and strive to improve it. The moral arc of the universe will not bend itself," she wrote.

"I'm with you all who are furious that our high school classmates who are bigoted and ignorant are celebrating early results," she said. Another post read, "I'm sorry to the younger voters for the actions of my Gen X peers who are full of hate."

"Helmuth stated that he respects and values individuals regardless of their political views. Although he has deleted certain posts, they were not a reflection of his beliefs, but rather a response to the election results. He clarified that these posts did not align with the stance of Scientific American or his colleagues. Helmuth emphasized his commitment to maintaining civil communication and upholding editorial objectivity."

After the election, Helmuth posted a Scientific American article titled "Election Grief Is Real. Here’s How to Cope," which included insights from University of Minnesota emeritus professor and psychotherapist Pauline Boss.

Previously, Helmuth held various positions as a health and science editor, digital news director, science and health editor, science editor, and news editor and reporter at different publications, including the Washington Post, National Geographic, Slate, Smithsonian, and Science.

Since its inception in 1845, Scientific American has been the longest-running magazine in the US and has published articles by over 200 Nobel Prize laureates.
