It does teach respect and fair play and so much more. The question here is, do they follow that? If they did, this world would have been a better place. I am talking big, I am talking about a whole entire universe,not two against one or three against five. If two Muslim countries are in war, why wouldn't people fight? The world is setting a great example. About the aggressive attitude, you think there isn't uneducated, uncivilized or unsentimental people in Egypt, there is and in a matter of fact in every country there is. They're the ones probably doing this, but they ain't doing it out of the blue, meaning, for no reason. It is because Algerians weren't really respectful when it comes to talking about Egyptians, they insulted players, people and our country. So basically that was the Egyptians respond to their rudeness. It's not like I am saying it is the right way to respond, but I am explaining why it happened.
I can easily swear at Algerians, as they all do (if you are aware that all the responds on Youtube are nasty) but I won't. Because I will not get down to their level, and overall such ignorant, are always to be ignored.
I do like my wisdom too, thank you, but "no" I am not being informed by anyone; it's what the eyes see and can't really deny.
