We don’t know the full story.
I would like to hear someone explain the full context, because I watched the video with the father speaking, and It is pretty apparent to me, from his comments, that the father is lock stock and barrel on board with the people that say Trump has somehow caused this atmosphere that encouraged the people who booed. Stockton went heavily for Hillary Clinton in the past election, has been under the Democrat thumb for a long time, and is known for going bankrupt. IOW, it is a liberal enclave.
Not saying those people on the flight were right or entitled to complain, quite the contrary, I think military families should get some consideration. But if the people were introduced as “a special military family” and that was it, how did the people know they were a Gold Star family?
It smells like Cindy Sheehan.
