I understand (and appreciate) the need to keep calm with Trump, but it's a fine line to walk (which is something I don't think people respect currently). You can't allow him to normalize his behavior, otherwise, he'll just endlessly push the envelope and legitimize his actions by further acting outside of ethical norms. And at the same time, freaking out makes people sound shrill, and when Trump really does have the big criminal scandal we're all waiting to drop, people won't be able to tell the difference between one apocalyptic sounding message from another.
All I've heard about criticizing Trump comes down to "We need to be quiet" and "We need to be loud." Not much acknowledgment of the difficulties of "Can't let him do what he wants, but have to save some outrage for later."
Sort of like how the criticism of Comey. Yes Comey made a lot of mistakes, but I don't really know if Comey needed to be fired. Only one FBI director has ever been fired before; they have 10 year terms and that's it. Since Comey helped Trump, it does mean that people are going to look for different explanations than "I really don't like how Comey treated Hillary Clinton." And if there were none, maybe people would think "Ok, maybe Trump is doing the right thing." But Trump's not doing it for the reasons he said he was.
