Please define "cancel culture".
Why don't you just read through the thread and see where it has been defined multiple times? Or you could google it.
It's pretty simple really, "cancelling" is when a mob, usually online on Twitter or other social media uses bullying tactics to attempt to force entities associated with a person who said something they find offensive to cut ties with that person. Entities can include corporations the person works for or is otherwise associated with, friends, family, or other associates. The primary goal is to silence a person, then to punish/harass/destroy them to the greatest extent possible. The "cancellers" are bullies, plain and simple, just like the bullies commonly found on school playgrounds. Like any bully, they use tactics including threats, harassment, intimidation, and sometimes physical violence. They're not interested in a debate, they're not interested in a conversation, and they're not interested in educating, all they are interested in is the use of force or coercion.
You've made it abundantly clear that you support this behavior, but just you wait, if it continues sooner or later they will come after you. Very few individuals can pass all of the purity tests, especially since they change over time and you can be punished for something you said or a photo that turns up from 20-30 years ago that has retroactively been deemed offensive.
I don't think you're actually interested in learning anything about it, but if you are, look up Bret Weinstein since that was one of the early victims. He and his wife sued Evergreen University and won half a million dollars, a bit low given what they went through and were accused of for the great sin of declining to participate in an "optional" and blatantly racist event but at least it's something.
If you still don't get it, then you are willfully ignorant.
