Your comment will take a bit of disentangling. For starters, it was Darat's claim that there was an attempt to cancel the Cardiff Philharmonic (I admit to thinking that maybe I should not renew my series subscription, but that is still on the table). He has yet to support that claim as given in comment #1464, although in #1473 he was talking out of both sides of his mouth.
My responses to comment #1474 was specifically in regards to Mr. Malofeev; I defined cancel culture and I showed how this incident fit that definition. There was nothing in #1474 about explaining why it was bad, although I did so anyway in comment #1477. David Walsh's article may be consulted for more information (link previously given).
Let me expand a bit on this one example. Concerts by Mr. Malofeev in Vancouver and Montreal were cancelled. The concert-goers who wanted to hear him were harmed. There is no logical reason to limit the canceled concerts to these cities, and if all of his concerts were cancelled his concerts, he would be out of a job.
Regarding Jason Kilborn, the students who could have benefitted from his teaching were harmed (I just read over his CV, and I was impressed, not that I am an expert in law). The same is true regarding Bright Sheng. The UW-Madison geology students were at the very least inconvenienced, and the $42,000 could have gone toward scholarships at UW-Madison, as just one example. Why wasting money is bad should be self-evident. Most of these things I have said before or were available through the links I provided. Do you ignore everyone's comments and links or just mine?
I am still waiting for other answers as mentioned in comment #1495.
