To your aside at the end, I've said here that I'm a bit skeptical about how new this problem is (I think it is more the case that it has become a trend to complain about it), but what I'm really pushing back on is the OP's casual statement of the premise that it is uniquely a problem of the political left, which I think is poorly supported.

To the rest: I agree that the definition used in the article was broader than just people getting fired. You asked me for examples of that specifically, which made me think you thought the definition being used was that more narrow one.
