While I could link to hundreds of example, this one example (out of hundreds) that occurred at a university is example of offense culture taken to extreme and weaponized:

Just the implication of possible offense caused this incident. Sure, the main culprits had other ideas, but the mob was there purely due to supposed offense. If you dare, you are welcome to look [1] the videos of the incident, it's horrifying.
And as a proxy, you can also guess just how guarded and buffered speech here is, and yet such events happen.
This is a slippery slope, and just because this happened for a few decades in the West doesn't mean it can't happen at all. And it's not the just the left, January 6 has shown that the American right are threat vector also..

Needless to remind you, it contains some NSFL material, I only linked because I think some education of reality is in order. This is the extreme end for the tolerance to offense.
