You know biology is just a theory, right?

Comedian Bill Maher blasted woke revolutionaries who think they can change human nature during his show Friday, drawing parallels between the woke movement in the U.S. and the Chinese Cultural Revolution.

During Friday’s episode of HBO’s “Real Time with Bill Maher,” Maher took aim at leftist activists, saying that they are actually fighting a war with reality and biology.

“If you’re part of today’s woke revolution, you need to study the part of revolutions where they spin out of control because the revolutionaries get so drunk on their purifying elixir, they imagine they can reinvent the very nature of human beings,” Maher said.
