Very well put. Ageism too. It's a way for the young to feel superior to the old without having to actually accomplish anything. Too lazy to study the past? Just say it all sucks anyway and even learning about it would morally sully you! Too dull to engage in complex arguments? Just slander your interlocutor based on their "outdated" language.

For some, it's an intellectual version of bullying the poorer and older and less well connected for having unfashionable clothes.

Paul Graham wrote in 2004 on this better than I could.

"What scares me is that there are moral fashions too. They're just as arbitrary, and just as invisible to most people. But they're much more dangerous. Fashion is mistaken for good design; moral fashion is mistaken for good. Dressing oddly gets you laughed at. Violating moral fashions can get you fired, ostracized, imprisoned, or even killed."

And he gave really good practical advice:

"Suppose in the future there is a movement to ban the color yellow. Proposals to paint anything yellow are denounced as "yellowist", as is anyone suspected of liking the color. People who like orange are tolerated but viewed with suspicion. Suppose you realize there is nothing wrong with yellow. If you go around saying this, you'll be denounced as a yellowist too, and you'll find yourself having a lot of arguments with anti-yellowists. If your aim in life is to rehabilitate the color yellow, that may be what you want. But if you're mostly interested in other questions, being labelled as a yellowist will just be a distraction. Argue with idiots, and you become an idiot."

The worst part of this is, say you have no intent to make rehabilitating the color yellow your life goal, but you see it as the morally right thing to do.

Not doing so is thus morally evil.

Hard disagree. I love dogs and animals overall. The fact that I don't spend my whole life managing dog shelters which we can all agree is a morally right thing to do doesn't make me nor anybody else automatically evil. Maybe in that saved time I am a neurosurgeon or fireman.

World is not binary, people even less so.

Not doing so is morally not the best thing. To say it is "morally evil" is to say that morality is some binary. "Evil" isn't a term I would throw around so easily.
