The political spectrum in the US is fascinating in the worst way possible. If there is a range of the political spectrum that more closely reflects reality, it contains a part of the blue, but almost everything else is outside it. So, if one were to sensor dishonesty, and preserve what's more factual, it would really not surprise me that, from a political point of view, its very biased against the right.
Then the question is if its correct to focus on the political nature of it, or the factuality of it. Imagine if one were to sensor a press conference from the White House based on factual correctness. Not much would get through, and one would say it is "Liberal sensorship".
In any case. I should know better by know that comments like these are not welcome. But, those were my two cents.
Doing the math: the "side" that holds power in a certain sector is the one wanting to control information. The best conclusion from that has to be "those in power want to control information to keep themselves in power", which makes a lot more sense than trying to attribute something as simple as "controlling information" to any particular political leaning.
