That's not the same as "content posted to HN and Reddit".
TBH, you're probably right that this article is going to have a viewership where supporting Trump is less likely.
The pushback you're getting is that you didn't make that claim, you made a claim that implied the Trump voter base was not interested in "long-form data driven thinkpieces", which is a brand of hubris that many are getting tired of.
The status quo on healthcare is not an option. Deporting every "illegal" is not an option. Banning Muslims is not an option.
I don't think Trump supporters are un-American, but I think they've forgotten some American values if they continue to support Trump the man. His leadership is the antithesis of America. If you're conservative, that's one thing. To be a Trumpian is to have missed civics class.
Here, watch this BBC video [1] where they interview Trump voters about their views on the "mainstream media" (by which you quickly realize they mean anything that doesn't deal in pure pro-Trump anti-librul propaganda). Here's an article [2] on a study showing that pro-Trump people specifically like to consume fake news shared via Facebook.
But personally I didn't really need a study to tell me any of that -- how do I know? I live and breathe and observe the world and people around me...
And yes, this is a generalization and not true of every single Trump voter. Obviously. All I really claimed was that Trump supporters will definitely be a minority of readers of a blog like this.

So weird how they all find their way onto the news. It's almost as if they were selected by image to fit a story.
