I can't tell if you are confused, or are intentionally trying to confuse others.
People were being fired. People were being shamed at scale. People’s careers were being ruined. Some committed suicide. All because of some shit they said online. It just shouldn’t be that easy.
You perhaps aren't familiar with our first amendment? What part of the world are you from?
Just because a million people hate you for something you said does not mean you should be punished as they see fit. Any punishment should be limited to social status, not employment or other societal benefits. Otherwise, why not just deny healthcare to racists, sexists, or people not aligned with the ruling party’s interests?
The issue is that the current president can't take criticism, and is ignorant of the Constitution. And a lot of people seem hot to excuse his unconstitutional actions.
You may not be able to practice discrimination legally, but in your heart and mind you can be whatever you want.
When you take that away from people, they no longer feel free, and they will retaliate like a caged animal.
Whereas groups of people can get together and decide to boycott whatever they want, government officials cannot direct such activities. That's the right to free association and expression protected by the first amendment. The only way you're ever going to get rid of "cancel culture" is if you remove that right. If people can't decide for themselves what they want to buy, and if they can't decide to associate with similarly minded people, there is no first amendment right to free speech.
And as bad as everyone says cancel culture is, no one has proposed a model where free speech is maintained yet cancel culture is forbidden. Most models proposed to are explicitly anti-free speech. The rest are just fascist, which incidentally that's the plan this administration is going with. So congrats, maybe you got rid of cancel culture, but you took down the first amendment with it.
