"being asked to substantiate my views with facts and evidence was unacceptable ideological bias"

always, it is known...

hard to skew those facts to fit their arguement. As youre well aware I'm sure, voter fraud in this country isn't one sided & more importantly doesn't sway elections. Voter suppression has its proof woven into the fabric of our electoral system

"The decades of flagrant, obvious, documented and often openly admitted voter suppression sounded just like Trump complaining that there is no way he could have lost to everyone in the Chik Fil A line. Why didn't my Times colleagues agree?"

He is extremely naive. One of the places Cotton wanted to send troops to is Seattle where the only thing that was happening was a Google bunch of people congregating on Capitol Hill intersected with normal street crime. Sending in federal troops would have turned the city into a warzone.

"'Both claims have the word "voter" in them,' I thought. 'Doesn't that suggest some deeper commonality?' I was to learn that such insights were unwelcome here, in the beating heart of liberalism's cultish fraternity."

This is the basic a projection always at work in all of these pieces. Conservative media types are mostly working from a set of anecdotes from trusted sources and so they assume liberals and leftists are too. They then want to compare anecdotes and figure demands for substantive data are bad faith.

Perhaps he thought heterodox meant not conforming to needing documentation.

"Studies show that the thing on the right largely doesn't happen. Studies show that the thing on the left does happen. These are equivalent to me."
