I guess I'm on the clear, because the affirmation "obviously, the majority are successful" was made without checking the exact numbers.
On my side, it's just a guess, but based on the fact that there are tons of universities, tons of events, and tons of people disagreeing with these events, I would say it is very reasonable to expect that if the majority was successful, the amount would be overwhelming.
> How come? If I go to a town square to speak and I get lynched, am I the one in power because I organized my speech?
But people don't just "show up" to universities and, bam, they can jump on stage and do an event.
The events are always vetted by the people in charge. The events and their contents are reviewed and agreed. If it was not the case, how do you explain that companies don't go there to do a "speech" that happens to promote their product, or that extremists communities cannot easily go there and do their sermon, or that politicians cannot just go there and do their campaigning?

Do you ever participate to such process? (not an attack, a genuine question. Maybe I'm wrong on how I imagine it works)

How do you judge "worst offender"? As I've said, it's very tricky, especially if the harassment from the "right" has become the norm. Or worst, when the harassment from the "left" is partially organised by the "right" (https://observer.com/2017/02/i-helped-create-the-milo-trolli...)
But does it even matter to the initial argument? Even if the "right" was the worst offender, the metric used in the article is still flawed.
And even if the "left" is the worst offender, if there is 95% of "right-wing" events cancelled and 5% of "left-wing" events cancelled, then, the presence of 5% is the demonstration that the left-wing is not in power (otherwise, it would be 0%).
More realistically, left-wing is the worst offender because they are the one using the protest tool more, while the people in power are not left-wing, they are just trying to ease the protest, but would act the same way if it was a right-wing demand.
