Trump and his press secretary deserved to be bashed, you can read his twitter feed or watch a press conference and see what a total fool he is, no need for any media to hype it. CNN, MSNBC, and Fox will typically have panel discussions that usually include at least one person from "the other side". I would rather have too much information and decide who is credible rather than be kept in the dark.
People are going to believe what they choose to believe.
None of the conservative leaning folks were complaining about the media when Obama was bashed by the conservative media.
