Nahh, its a principled stance. It's a hard concept to explain but I will do my best. This will kind of diverting from the topic, but its necessary to explain, observe the following video:
Now one could argue, why didn't the Imam run away? Many behind him ran away and it's totally allowed in Islam to break your prayer and protect yourself during circumstances like these. But it's also about principled stance and belief, one could choose not to run away.
We aren't the people who eat rats and crows, when dying of hunger. While some can because it's totally allowed in Islam when you are dying of hunger. But then again some people take principled stance, it has nothing to do with arrogance.
Sure the situation in the OP's video wasn't exactly the same as the hyperbole's I am discussing, but it was still disrespectful and disgraceful, like I said in my first comment.
