This Dr. Dao guy is not necessarily on solid legal ground on the second point even if he was absolutely right on the first one. If you get arrested for drunk driving and you know you haven't had an alcoholic beverage in months, you may be ultimately vindicated but it doesn't mean it's a good idea -- or even legal -- to resist arrest on the side of the road.
Dao was non-violent so in theory there was no need for him to be harmed. Who did Dao harm? If he harmed no one, then the airport security escalated force.

and how does your analogy fit the united passenger?
If it was you, and your wife and child were on the plane, would you deplane or would you argue with them for wanting to remove JUST YOU ?
Remember, you will be stuck at the originating airport, your luggage will end up at the destination airport, as well as your wife and child who will be stranded there and possibly have no where to stay and no funds to use to eat.
WHY did the airlines choose a passenger who had FAMILY with him ?
