If fox, newsmax, and OAN are the only ones willing to report on certain topics earnestly, like, say patterns in black on asian violence, or other ethnically sensitive issues, then yes, their voices are critical to a functioning democracy. The way that news, entertainment, social, and "fact checking" media all effectively collude to discredit these sources for political leaning is dangerous, and in effect disenfranchises about 50% of the populace who do not lean left, in the online public sphere. This is an unstable configuration. Dismissal of these sources conflates political bias with unreliability. It's disingenuous, especially when outlets biased to the same degree but in the other direction are de facto approved on Wikipedia, reddit, stackexchange, Twitter, etc.
You notice the growing hyperpolarization in this country? This is one of the main contributors. The left has monopolized public discourse and implicitly and increasingly colludes to keep right leaning sources discredited and silenced. YouTube's removal of the video in the OP is one of many examples which consistently align with the sort of progressive policies that are now sweeping the corporate sphere - and rural Americans are losing their voice, while being slandered as ignorant bigots. Go to the talk page for any remotely political article and you'll see a minority of right leaning editors consistently bullied and their sources outright disregarded. That's on top of the chilling effect which this consistent behavior has on the expression of what have become politically taboo opinions. It's an unspoken, incestuous club, and denying this pervasive bias is gaslighting.
