It certainly isn't about ONLY ALLOWING speech and ideas and beliefs and teachings that YOU approve of or that YOU find correct.
An airport is not a public place as is the street corner. Do you know anyone who would say that, letting your child die instead of using ALL medical support to save them, is an approved teaching and belief?
How many non-Witnesses do you think know the blood issue about Witnesses? I suspect the admin at the airport didn't. I know if I had that resposability, I would want to be informed.
