There are a lot of examples that someone is criticized without considering his/her background.
For exampled, Iyo Matsumoto, middle-aged actress in Japan, was arrested after she stepped in tracks of JR Sagano Line to take pictures.

And, her high income and status deprived her of the chance to board local or commuter trains and to know current manner about trains.
So, when we criticize something, we should imagine what's behind it.
