Tucker's not allowing his audience to see Alex and decide for themselves. He's selling them on him and promoting Alex as a prophet. Tucker wants to pretend that Alex is this entity that's so challenging to the system and it's a revolutionary act for him to have him on the tour stop because that plays into Tucker's own self-image. He can pretend that the goal is to let the audience decide for themselves about Alex, but Tucker hasn't even looked any deeper than an edited clip to decide that Alex can see the future. Why doesn't Tucker look a little deeper and see for himself why people might not like Alex? Probably because to do so would jeopardize their ability to make a shitload of money playing this false iconoclast role.
