When a local fly fishing guide spotted noted vaccine skeptic Tucker Carlson at a sporting goods store in Livingston, Montana, he did not waste time.

“You are the worst human being known to mankind. I want you to know that,” Dan Bailey can be heard telling the Fox News host in a video posted to his Instagram page Friday night…

In his Instagram caption, Bailey wrote, “This man has killed more people with vaccine misinformation, he has supported extreme racism, he is a fascist and does more to rip this country apart than anyone that calls themselves an American.”

Much of the brief conversation ― apparently filmed by a shaky mobile phone ― is difficult to make out. Carlson, in a plaid button-down and a gold watch, can be seen holding his hand up against Bailey’s chest, making his trademark exaggerated facial expressions. He appears to grimace, and then, realizing he is being filmed, spreads his mouth into a grin and turns away.
