Giving into left-leaning fashions is bad not because of the "left-leaning" part; its bad because of the "fashions" part. It's lazy groupthink at best, and bullying people into conformity at worst.

Have you noticed how narrow and specific all of the rules for reporting have become? Do you honestly believe that leftism is defined by these narrow rules, many of which are changing rapidly?

No. Most left-leaning people don't believe this stuff (how could a normal person even change their beliefs from one day to the next?). They go along with it because either they are too scared of getting bullied themselves; or because it's mostly hurting the right, and they believe they can regain control of the discourse after the right is diminished.

But it's easy to destroy good discourse and hard to rebuild it. After the right gets marginalized, we won't go to open-minded chats over coffee among left-leaning folks. It will be these same horrible tactics over the most minor differences of opinion on the left. Proponents of socialized medicine will be doxxing proponents of Medicare for all. There will be no end to the ridiculousness.
