For actual left bias, see: the baffler, the intercept, jacobin, mother jones, counterpunch, the nation, and oddly teen vogue. If PBS is left, those are surely falling off the spectrum.
Finally podcasts cater across the spectrum. I can’t help with specific examples here, but you can certainly find anyone from anarchists and communists to democratic socialists to liberals to libertarians to blatant far right wing shit (monarchism?, “racial realists”, “trumpists”).
I can't remember ever seeing a "right-wing" viewpoint in Bloomberg's opinion pages. As far as I can tell the only op-eds they publish are pro-gun control, anti-income inequality or just generally anti-Trump.
One of those things is not like the others.
On the U.S. side, intellectually oriented conservative media has really had trouble with the Trump era. The more highbrow outlets were never on board with Trump, but maintaining an anti-Trump or Trump-skeptical line on the U.S. right basically dooms you to irrelevance in the current climate, since only a smallish band of "never-Trumper" conservatives are still tuning in to that political position. There are a few of those, like The American Interest, which keep going on a small circulation.
If I wanted a counterpoint to PBS's left-leaning biases, where could I find content with a right-leaning bias, that isn't sprinkled with religion, screaming hot heads, and other unpleasantness?
