I think Trump has many character flaws (and that's putting it lightly), did many not-so-good things, etc. It is fine that this is highlighted by the mainstream media.
My main problem is that the same treatment is not applied to the democrats. This means that in order to find similar stories from the other side, one needs to start (1) reading extremist-leaning news. These also contain many half-truths and outright lies, so on top of that one has to (2) try to verify themselves the veracity of those claims. Most people don't have the time to do that (obviously), so they stop at the first step.
