My pet peeve concerns dishonesty, misrepresentations, and mischaracterizations....not typos.
But, as regards typos and/or grammar errors, that is about the only time I ever see that you and your ilk are consistently genuine about your concern, or its enforcement, valid content or context be damned.
Another pet peeve of mine, interestingly enough, is the attempt to excuse a clear error by labeling it a “typo.”
