I'd consider myself extremely left-wing, but I'll give it a try:
They're right about the media having a liberal bias. For every Fox News clip or soundbyte out there that would piss me off, I'm confident I could match it with an equally partisan MSNBC clip. And chances are, I wouldn't have even noticed how biased it was because it simply felt good to hear. Especially right before the election. I remember realizing that every single talk show and TV personality I followed stating bluntly that Trump must not win. To be clear, I agreed with their arguments almost 100% but the lack of any sort of "devil's advocate" kinda freaked me out.
Gun control really is a much more complicated and nuanced issue than most liberals seem to give it credit for. Same with immigration.
Donald Trump mocking Ted Cruz for "New York values" comment was legitimately awesome. I wish the Democrats would call their own people out on their bullshit like that.
