This is probably my leftist bias, but ever consider that "leftists" are more interested in laws and decency whereas "rightists" are more interested in protecting their tribe/movement? But you think both sides play like "the right" (each only interested in exposing flaws of the other side) because you're seeing from your right-leaning perspective...
Democrat Al Franken got kicked out of Senate when it was found he inapproprately kissed a woman. I can name a long list of creeps in the GOP side who received protection from their side. Matt Gaetz, Roy Moore, Sexual Harassment Hegseth, Epstein-Friend in Chief. The GOP doesn't seem to have any principles about which sexual deviant they have, they just care about having the majority (in congress) or the power. Oh yeah, speaking of that, sexual assaulter Justice Brett M. Kavanaugh...
I'd trust left-leaning media to report wrongdoing whoever does it, whereas right-leaning media will gloss or bare-face lie about wrongdoing done by the right, and exaggerate about wrongdoings by the left...
It sure feels like there are people who care about formulating and holding principles (e.g. "adultery is bad") that ought to apply to everyone, and then there are people who pretend to do the same but all the "principles" are just reflections of some ultimate virtue of loyalty/obedience, towards some hierarchy they consider existentially important.
The first group will define good/bad acts and then judge people by what acts they commit. The other will defines good/bad people, and then judge acts by which person is doing them. If you want investigative journalism, clearly group #1 is preferable.
On a similar note, I highly recommend a playlist of long-form videos from ~2016, titled (in the sense of an expose) "The Alt-Right Playbook". In particular, the video "Always a Bigger Fish" [0] tries to make sense of some persistent "how can they possibly believe X but not Y" disagreements when it comes to democracy and egalitarianism.
