What is it With the Left and Free Speech?

I am noticing a disturbing pattern among the Left when it comes to Free Speech. What started this process was Ken Thornton at Electric City Weblog who said

My standard is the old fairness in broadcasting standard. All the mainstream media did fine and democracy did well under that. About 1988 was the death of that standard and the death of our democracy. Its death ushered in Right wing radio and Fox News and the false reality they create. The truth suffers and so does our democracy.

(Emphasis added)
The false reality is an interesting approach. Do those on the Left believe that anyone who watches Fox News thinks up is down and vice versa? Are the colors all reversed in their imagination of what those who watch would have?
Ahh, but Fox makes errors, there is no doubt of that. And if that were the standard there would not be a CBS News. Although to be fair, they did end up describing it as "Fake but accurate." And don't even get me started about the New York Times. The paper of record is becoming almost half the paper of corrections. And MSNBC? Their journalistic bona fides are best demonstrated here:
But it goes beyond just which news the Left is going to validate as being "accurate." Senator Bernie Sanders, (Insane, VT) wants to tell people who can own media outlets. This is a repeat of the canard that all news is philosophically conservative because it comes from corporations. This amusing logical fallacy has been refuted so many times, I won't waste your time here.
This is all part of the reaction of Citizens United decision and the removal of restrictions on corporate speech.Ironically, Democrats who keep tinkering with the corporate tax code, and as a result are driving business overseas, now don't want to hear from those same businesses when they are considering said legislation. The Left would be fine to allow unions free speech, but they demonstrate their ignorance when they think unions can exist without businesses.
The absolute lack of understanding that political speech cannot be regulated betrays the concerns that those of the Left are less likely to hold the Constitution in the honor it deserves. These are the same people who claim to protect constitutional rights. But it appears only those rights of abortion. All others are subject to suppression.
