So do you want reality or reality TV on Wikipedia? Should we consider Ancient Aliens as a source?
I've seen the actual news that comes from them and while it's certainly biased rightward, particularly in what they choose to report on, it's not outrageously so.
Anyways, to get off-topic from my original comment, here's some evidence for you to ignore:

He's so unable to engage with ideas he doesn't agree with that he's conflated having a stance with "bias".
The counter-arguments to all this all tend to boil down to some form of condescending tone or moralizing:
* left-leaning is just reality-leaning. LoLoLoL right-wingers are sooo stupid!
* Wikipedia should take the left-leaning stance because it is good, moral, noble, and righteous, while the right-leaning stance is vile, evil, unconscionable, and despicable.
If either of those thoughts cross your mind, then, congratulations, you are left-biased. You should try your hand at Wikipedia article editing. I'm sure they'll love you.
He first invents a link between a topic being "complex" with not being able to take a side. Then he conflates taking a side with "bias".
This is detached from reality. That is not nitpicking words. This is a word salad that starts with a need to dismiss a viewpoint and works backwards.
This "co-founder" was let go from Wikipedia in its first year over 20 years ago. He's had a crusade against them ever since.
