I hear ya. I look at it from a slightly different perspective and that is at least there is some exposure of how Arab hospitality is like. As long as that doesn't change or is taken away and some see it, that's more important than the ungratefulness or the lack of wanting to expose such a thing because God forbid any outlet that isn't Arab or Muslim showcase the good hospitality that is from Arabs and Arab countries. The same would happen if it was in Saudiya, UAE, Egypt etc.
And hey, if it ended up on Twitter then you can bet millions of westerners saw it. And the clever part about the title is that it starts out making you think that that it's a bad thing, or that they would greet them with vulgar swearing about the US and the wars and the innocents Muslims that got killed in those wars and especially the US' support of Israel. But then suddenly it shows kids and adults passing out food and treats LOL! It's actually brilliant.
