Yes, in a sense I think it's true that the "traditional media" is probably mostly staffed by people who tend to oppose the Trump presidency. But this is for two very specific reasons:
1. Trump ran a divisive campaign that was in many ways--perhaps primarily--a campaign against both the demographics of most media reporters and the actual institutions of media itself. Reporters, being humans with feelings, probably did respond to that a bit.
2. Trump ran a campaign that was founded on literal falsehoods.
Extending reporters some degree of professional respect, I tend to believe #2 is the primary factor here.
The terrifying equivalence here is between "traditional media" reporting factual truths where you can kinda-sorta-sometimes tell that the reporter probably doesn't respect Trump as a candidate and "alt media" reporting things of huge consequence that never happened and have no basis in fact.
Those are fundamentally different things, and what truly worries me about both the stupid shit like "pizzagate" and the significant lies (on economic measures, on science, on documented reality as we know it) is that our politics appear to have become unstuck from consensus reality.
There's no rational discussion--and, I believe, truly no hope for the democratic process--if we're not arguing about mutually agreed-upon facts. Yet that's where we are.
