It is bias if your "factual reality" over-exaggerates the "facts" for the "bad guys" and under-exaggerates / completely neglects to report on the "good guys"
But to put it with John Steward, what if reality itself has a left leaning bias?
What if left leaning people have empirically broader empathy [0] which could imply that right leaning people have in tendency worse personalities. I guess you would attest yet another biased article here.
There are also genuinely good guys and bad guys. Reality, itself, has a bias. To think that ideology doesn't correlate at all with how moral you might act is, frankly, stupid. Not all positions are created equal.
