The advice doesn't matter . Anything can be labelled as "sexist" nowadays, and you can find yourself on the "cancelled" end just by interacting with the wrong type of person. Case in point, the very story we're discussing - raising the pitch at the end of a statement. There's nothing sexist about giving advice to correct that, because men do it too. However, the wrong type of person will project their sexist views onto the situation by claiming that it's something only women do. With enough pushing-the-right-buttons from that person (these types do seem to be relentless), you are now branded a sexist and cancelled. The patients are truly running the asylum these days.
