People naturally form us-vs-them tribal mentalities, and the fact that this is the top comment of this post indicates that its a tribal mentality that's leading it to be upvoted.

It's like saying on a Roy Moore post that the investigation was carried out by CNBC: it leads to Republicans invalidating any finding of the investigation. This default of ignoring any information from the Other Side is what almost got Roy Moore elected.

This us-vs-them mentality needs to be noted. The fact that this comes from a think tank does not immediately mean they don't raise a good point.
