A clarification here: I believe this anti-American was not on the plane in question, but posted her objection as a hypothetical.
I'd be more that happy to post my dislike of this individual, but as a conservative, I'd support her IF she had actually been in the situation.
As a customer, an individual trapped in such a situation......and found it objectionable for any reason, religious objections, noise, simply a grumpy ol' fool.......she would be within her rights to ask for quiet.
It's not as if she could simply get up and walk out.
