"The desire for more positive experience is in itself a negative experience. And, paradoxically, the acceptance of one's negative experience is itself a positive experience."
from "The Subtle Art Of Not Giving A Fuck" by Mark Mason
The Enchiridion of Epictetus is a good place to start. You'll also learn how to feel when your favorite mug drops, or when a friend pokes your eye in a wrestling match - spoiler: the answer is not giving it a fuck (for lack of a better term).
"The problem is not that we want to be happy; it is that we want to be happier." Not my own observation. But I like it.
If that's a general principle, it implies that happiness can only be felt as an improvement over the past. That would also explain why sadness is necessary for us to be able to feel happiness, and why we're attracted to tragic art. Someone who is the same level of happy all the time will become numb to it, but constantly becoming happier is unsustainable in the same way as a drug addiction.
Yes. For examples of this trend, look no further than American college campuses, especially in the liberal arts.
"Microagressions", "safe spaces", ... it does sound like a lot of people feel untenably fragile when entering the marketplace of ideas.
I think your thoughts are incomplete. What they are missing is the knowledge of and empathy for people who are actually harmed by these behaviors.
Don't worry, most people asking for such bans don't have any real empathy for people who are actually harmed by these behaviors either.
And inversely, most people who are actually harmed, don't care for such bans, they prefer substantive and inherent (felt and voluntary) changes, not bans.
Let's not pretend there aren't plenty of cynics that employ woke culture to sinister ends.
A couple years ago I dubbed this trend "Flanders Computing" [1]. I haven't really given much thought about its origins, but it's probably got to do with the increasing demand for happiness that we Americans hold dear.
Collectively I think it's entered the American psyche that the answer to happiness is to avoid anything that makes us anxious or uncomfortable, which results in that toddler-level approach in many things. i.e. Ban things labeled "toxic", ban the boo-boos, keep everyone safe with happy feelings in this space only. But admittedly my thoughts are incomplete.
