Whataboutism is a phrase used by liberals to excuse hypocrisy
Washington Post Editorial:
The media got that label when they decided that Trump was so bad he did not deserve to be treated fairly. Even since then the media has gone 90 to 95 percent negative in its stories about Trump and his supporters are tuning them out. Meanwhile conservative voices at Fox and shows like Rush Limbaugh are more popular than ever and the liberal media remains in a funk.
