No...no it isn't. That is exactly what didn't happen.
Brietbart, Fox..Drudge, Rush, Infowars...all went relatively UN-checked. They expanded their platform while the left patted themselves on the back. NOT the other way around.
The people and these platforms went largely ignored by the elitest left, and they lost an election because of it.
Ignoring harder is not going to work.
Your entire basis for arguing against it is flawed, because -
If only someone had just beaten Trump in, I don't know, three different debates, he totally wouldn't be president right now
You're operating as if logic and reasoning is going to dismantle their arguments. It won't, it doesn't, and it hasn't. The left weren't
just patting themselves on the back. They fact-checked, and tore down every poorly-phrased word salad that Trump spewed out. That's how 'alternative facts' were born. A phrase that should have absolutely zero relevance in modern discourse, but was legitimized and is here to stay. The same now applies for Milo, Bannon, and the rest of them.
It's not like I don't see what you're trying to say! But, we've seen a considerable shift in the overall conversation that has illuminated quite a lot about how they clawed their way to success. What you're thinking is, unfortunately, divorced from the reality we live in now.
