I have to spend irreplaceable moments of my life explaining to my own family that vaccines won't cause autism. I'm well outside the filter bubble. Fox News is like sewage, in that yes, I'm aware of its existence, but no, I don't want it mixed in with things I consume daily.
The little I’ve watched Fox News, while the opinion pieces are one sides and dishonest and they do choose what not to cover and what to emphasize, I haven’t seen any indications that they cover outright conspiracy theories.
Out of the conservative news sites though, I do find that RedState and the Hill to be more honest.
