It's not that I disagree with liberal objectives, and certainly not worldviews. However, I find that I cannot join in on imprecise criticism.
Imprecise criticism is dangerous to anyone's cause because it reduces traction and gives fodder to the opposition who senses and interprets it to mean the argument as a whole is wrong. A good example is discussing immigration issues. Countless political commentary pieces, politician speeches, and even the news headlines themselves, use the one-word term "immigrants" when they really mean "illegal immigrants".
Trump is another example. It's probable, even if he "fixes" the economy, that he will be destructive in other, larger ways, if only due to his lack of government and political experience. He himself is one issue but the people he has stocked around him are like a sitting coalition of every nutty right wing commentator picked from the comments section of a news site. This probably isn't going to end well even as we happily sit mesmerized by money moving again.
Yet we can only reasonably criticize outcomes, all other factors being what they are. There is today's unemployment rate, number of people insured, today's crime rate, today's commitment of troops to policy wars, and so on, all of which currently read well. When these dials tank, if they tank, then will be time for real criticism. Conservatives tend to "re-factor" the argument rather than abide by the simple reality that Trump must maintain Obama's high standard of progress to be considered successful, following him.
There are things along the way that despite those metrics will also be credible points of criticism. Getting behind or failing to stop policies that facilitate the conversion of the open web to cable-TV-like, for example. Staging us for unnecessary wars, or sinking the standard of reason and principle so low that every adversarial nation will smile with friendship as they sink their knives in. Witness the Trump/Russia "alliance against America" as one example. But all of these are only hints, not yet materializations, of a declined US by Trump's hands. Criticizing by emotion is never as handy as criticizing by data. Give the policies and the man a chance to actually fail before muddying up the water with hyperbole, and be precise with any and all arguments that apply now and (most certainly) then.
