Media Bias Fact Check ranks Reason as a "Right-Center" biased website with a "High" rating for factual reporting: https://mediabiasfactcheck.com/reason/

They certainly approach stories with an editorial perspective, but they're generally factually reliable and hardly "incredibly slanted".

Reason’s libertarian bias sits outside the mainstream Left-Right axis of US political discourse.

So what looks centrist or right leaning on a 2D scale is actually heavily biased in a different political direction.

Yes, thank you for pointing this out – but they do tend to report the facts correctly.

I don't think there's much Left in US politics, unless you mean in the language of US politics, where somehow Democrats are considered "Left".

That website calling CNN moderately left instantly destroys its credibility

[jasonlotito]

“They often publish factual information that utilizes loaded words (wording that attempts to influence an audience by appealing to emotion or stereotypes) to favor conservative causes“

So, when they present facts, they surround them with emotional words to try to sway opinion.
