I've never uttered the words "CNN is unbiased". In fact, bias exists everywhere. You, me, even Mr. Deez has a bias. The key is to understand the bias.
I was responding to your point that XX+XX+XX+XX new channels all were talking about the same thing. That's reality. Donald Trump did foment the unrest starting with his tweet on 12/19 that said "protests are going to be WILD!" His consistent claim of fraud before the election and after the election without evidence, even after losing 62 of 63 court cases. Guiliani further incited the crowd when he screamed it was "trial by combat" and Don Jr. of course added his own threats to anyone who stood up to them promising to "be in [their] backyards next week".
Reality can sting. It hurt those on the left when peaceful and justified George Floyd protests devolved into riots and looting. Those actions certainly ceded some of the moral high ground from what was a righteous response to a cold-blooded murder. Looting and rioting have no place in our democracy.
