He does not mention anything about stars. He is pointing out that the type of people that go to an event like this is going to heavily skew left. The left drones on about paper straws and saving the planet, yet cannot be bothered to even pick up after themselves. The point does not hinge on whether or not it was movie stars, but on the exact kind of people that would even go to the oscars (You see this same thing at just about any leftist rally, garbage everywhere, it shows that they don't believe their own BS and it is all performative.)
