Flipping out about the nomination of Wilbur Ross, for example, as Secretary of Commerce detracts from the weight of legitimate arguments against many of Trump's other picks.
To many journalists' credit the reaction quickly quieted down once his record and character become more clear, but first impressions are sticky. Now journalists and pundits, especially liberal-leaning pundits, will find it that much more difficult to constructively criticize Ross or other officials in the future given that it's established that they wrongfully flipped out in at least one significant case.
You make fewer of those mistakes when you stick to concrete facts and concrete policy points. And it goes without saying your arguments will be all the more sound for it.
Yes, Trump's rhetoric is anxiety inducing, and there's plenty about his track record, including as president-elect, that evidences he's willing and capable to follow through on much of it. But there's also evidence he won't follow through on some of it. If he doesn't then he can claim people were crying wolf. He probably will do this strategically. Certainly his rhetoric is strategic.
Unfortunately we won't be able to get off this roller coaster for at least 4 years. But that doesn't give everybody carte blanche to start screaming their heads off right out the gate.
Look, plenty of other countries have had to deal with, and are dealing with, demagogues. We know how to do deal with it. Keep your heads on straight and stay vigilant.
Anyhow, if people are right about Trump, there'll be plenty of opportunity for [more] outrage. If there's not, then all the better.
