Shame? Having to get patted down and trying to explain your disability and why you need exceptions in a place where TSA acts like God? It's entirely different. It's as different as choosing to come out or being outed. I sympathize with people with disabilities, they know that people are sympathetic and it's very awkward to have to make excuses for yourself for a disability you have no control over.

On the other hand, in your own forum while making a point, it makes perfect sense to use that context to explain why it was embarrassing and is in need of proper training or policy modification.
