Is everything that NBC or CNN reports a lie because they've been caught fabricating stories in the past? Is that enough to disprove any fact, just attacking the source?
No, and I thought I clarified my meaning a couple of pages ago. PragerU makes a lot of well-researched videos with excellent production value, and obviously everything they claim isn't automatically false just because they've willfully misinformed people on climate change.
But my original post was asking why intelligent conservatives constantly post
their videos, rather than just the evidence which PragerU sources from? Why present your arguments within the framework of people who have a proven agenda to misinform?
I don't even think comparing it to NBC/CNN/FOX/whatever is appropriate because at least those kinds of networks are stratified and syndicated. Sean Hannity might claim that Hillary murdered Seth Rich, but he's still somewhat of an independent entity that Fox has the power to punish for bad journalism. It's highly unlikely that there was only one producer/creator on the PragerU team that was responsible for making all their awful videos about climate change.
