Agree, this is like banning the tabloid magazines at the grocery.
Infowars has plenty of crazy nonsense, but they also have plenty non conspiracy theory content involving politics, etc. Hell, look at Alex Jones documentary inside Bohemian Grove, that documentary alone proves that Jones is not 100% full of shit, though I'd believe he's close to 70%.
Furthermore conspiracy theories and fake news are mutually exclusive by definition. If a conspiracy theory were proven incorrect, in which fake news must be, then it is no longer a conspiracy theory.
Exactly, any blocking of media sources for news(bogus or not) is basically public thought control no matter how trivial the outlet.
