What did the child sitting in the exit row do to you? Did it increase your risk of dying in a plane crash? Heck, the risk may have even doubled from 1:100,000 to 1:50,000!! You were in much more danger in your taxi ride to the Doha airport. Chill out and get some perspective.

You shouldn't proceed. You should take a deep breath and realize that different cultures have different laws, different priorities, and different risk tolerances. The family and the FA probably assumed you were just trying to poach their good seats, and treated you with appropriate scorn.
