But as Bsmurf points out,there's a segment of the population that don't believe certain objective facts. Democracy demands debate and scrunity and those who cannot accept whats fact and whats not make debate impossible. The demographics of these people tend to be older, more religious, white and live in rural communities.
So one shouldn't generalize - assuming those have a reality gap represent an entire group of people is wrong. Period. But I also dont think its wrong to be intolerant of those who don't accept objective facts because they've been exploited by the GOP for their political gain. Considering how severe the cultural gap is in this country and how Trump won the election despite losing the popular vote (a fact, I should point out, denied by the segment of the population because of Fox News, Breitbart, Infowars and the like) and winning electoral votes in states where the minority of voters voted for him, this becomes incredibly problematic. The party in power doesn't have the backing of the majority. They are really just representing the thirtysomething percent that have a reality gap.
Politico had a good article about a community of Trump supporters in Pennsylvania that will never lose their faith in Trump and believe everything he says even when they are lies. For them, its all about hate. Trump hates the groups they hate - Democrats, the media, coastal elites, and especially black groups that advocate for issues that affect their communities. The people interviewed don't have any clue what they are talking about. One of them said: "Everybody I talk to realizes it's not Trump who is dragging his feet. Trump's probably the most diligent, hardest-working president we've ever had in our lifetimes. It's not like he sleeps in till noon and goes golfing every weekend, like the last president did." When the reporter told him that Trump golfs a lot more than Barack Obama, he was surprised.
So DTXBro is loud and may cross over into generalizations on occasion, but I don't think he's trolling. I sympathize with his frustration.
