Clearly she's a serial whinger, but I agree with Bose, Contacttower and others. She has a right to her views and has a right to air them, however irritating, ill-informed and self-serving they seem to be. And we have a right to put our views, as pleasantly but as forcefully as we can, and to present ourselves as exercising our rights while being mindful to minimise the inconvenience and annoyance to others. Live and let live.
In this particular case, it's not hard to correct the many errors in what she says, all the while remaining reasonable in the face of her silliness.
