What needs to happen for shit like this not to happen anymore.
There are two possible interpretations why it's happening: The benevolent perspective is that the political right has enshrined the "free market" as not just a heuristic that has served us well, but as an ultimate goal of politics itself.
The less benevolent interpretation is that it is precisely the opposition from consumers and everyone with expertise that makes ending net neutrality so valuable.
Almost any connection of reality, and the power of reasoned arguments, has disappeared from US politics. As seen with the efforts to repeal ACA, there are maybe three or four Republican Senators left who can be influenced with either appeals to reason, humanity, or who simply have a constituency that forces them to do so.
You cannot change this dynamic with arguments. You need to heal the culture wars. Somehow.
Case in point: a judge, who was twice removed from the bench because he fundamentally disregarded the most basic tenets of the rule of law, such as the Supreme Court having the power to overrule other courts, was the prohibitive favourite in his Senate race. He may still win, even though it is proven almost beyond any doubt that used creep on underage girls[0].
I wish I could give similar examples for the other party. But it'd just be an excursive in false balance. However, I wouldn't rule out such behaviour by voters from the other side. It's only that until now, that party and its candidates would not have had the chuzpe to just cry "fake news" and stay in the race.
Anyway: people have become attached to their party as they do to a sports team. They self-sort into states with like-minded people. The culture wars creep into anything, so that even the sports you play or the restaurants you visit will be politically homogenous.
It is quite obvious from above what my "team" is–and I'm not even a US citizen. What I try (and failed spectacularly in this post), is to apply a certain level of intellectual rigour even to "my team's" arguments. I also go out of my way to show appreciation for any acts of reasonable behaviour by people on the political right.
Two examples that come to mind: I had tears in my eyes, and frequently mentioned, John McCain's graceful correction of a citizen at a town hall who called Obama a "muslim terrorist". I have also defended the current President's airstrike against the Syrian government after their latest use of chemical weapons.
