Watch Bill Maher's face when Neil deGrasse Tyson refuses to define a 'man'

Bill Maher’s “Club Random” podcast has certainly stayed true to its name by hosting an array of random characters.

One of the latest is Neil deGrasse Tyson, who believes so much in science that he can’t define what a man is.

“What is it that makes the man the man? Is it the hormones? OK, if it’s the hormones, and you decide to give yourself a different cocktail of hormones,” Tyson tells a laughing and then stunned Maher, “... maybe the track meets have hormone categories.”

Maher notes that giving yourself hormones can be harmful to your health, but Tyson has another “scientific answer.”

“You’re so deeply concerned about the health of the people who are trying to find their place on the gender spectrum? You care about their health so much that you don’t want them to go through that?” Tyson rants.

Maher admits, “It’s not something that keeps me up at night, but when the subject comes up, I care about them like I care about all people.”

Dave Rubin is impressed with Maher’s way of handling the conversation. When Tyson attempts to keep the fight going without making a point, Maher shuts it down.

“At that moment, he’s proving that the good liberal can still exist,” Rubin says. “Tyson is trying to dismiss him like you don’t really care about these gender-confused people.”
