Earlier quoted context omitted.
I think engagement is part of the problem - many people are very eager to spot "gotchas!" of their opponents, rather than taking a more broad and measured view. And educational achievement doesn't seem to be any barrier to the acceptance of bogus news - even being a leader in one field doesn't make you immune to disinformation from an unrelated quarter, and in fact we see this every day.
I assume education would encompass critical thinking, allowing for the neutral evaluation of multiple sides of an issue, and a critical eye toward the veracity of facts and news consumed.
On the other hand, I can't help but think comment threads like this amount to nothing more than "voting for the other guy is so illogical, clearly my vote is the correct one". A slightly veiled way to call anyone who doesn't vote your way stupid.
