Is Fox really this delusional or do they think their viewers are this stupid?

I keep thinking that Fox thinks that their viewers are so incredibly stupid that they can't remember a few years in the past, but maybe they just are so delusional themselves that they convince themselves that these absurdities are true. I mean, how do they even say things like this with a straight face?
