New York Times columnist Paul Krugman argued on Twitter Tuesday that the results of lifting the mask mandate on flights could be even worse than people fear.

U.S. District Court Judge Kathryn Kimball Mizelle struck down the federal mask mandate for airlines. Videos soon emerged of passengers cheering the end of the mandate during their flights, however several liberals and media pundits criticized the decision and specifically called out Mizelle.

Krugman offered his own opinion on his Twitter account, claiming that this new development could actually lead to more violence.

"A prediction about masking: Soon we'll be seeing many incidents in which those who choose to protect themselves with KN95s etc face harassment, even violence. Because this was never about freedom," Krugman tweeted.

Critics responded to Krugman's prediction, often with mockery. 

National Review senior writer David Harsanyi tweeted, "By 2025, or so, it will become clear that the mask's impact on our health will have been no greater than the fax machine’s."
