Why the Anthems all the time?

I don't get it, i really just don't get it.
Why do Americans and Canadians feel as though they have to stop in there tracks and sing there National Anthem at virtually every sporting occasion?

Coming from England, i only really heard `God Save The Queen`sung at International Sports Finals, and that mainly being in Football, Rugby, World Cup & Olympics (the last being if you win).
Here in North America i feel as though they have an identity issue and feel as though they have to constantly spew out the Anthem just to remind you of where you are.
It`s sung at all NBA, NHL, MLS, NASCAR.....  to be Frank, they do it for every North American sport!

Two weeks ago i went to see Toronto FC play Kansas in Toronto.  As i tried to make my way to my seat in time for kick off i was held back because the National Anthems had started. Pardon?. National Anthems, for who?.
This for one is not Canada v USA, this is club level MLS Soccer,  Toronto v Kansas.
Secondly, half of the players on the field are not Canadian nor American!
But what i did notice was the over the top Canadians over reacting in my opinion to singing it. Guys, the chap from Peurto Rico on the pitch doesn`t give a shit!

Prior to this, On July 16th i went to see Manchester United (GB) v Celtic (GB) play a friendly at the Rogers Center in Toronto.
I was speechless when we were all asked the following ``Please stand and remove your hats for the singing of the National Anthem``.
God Save the Queen? I thought to myself,
Oh no! Oh Canada!
Hang on, it`s two British Teams playing, so if anything it should be there anthem. Nope, time to make the insecure feel secure again, Ò Canaddur...``

If you should venture out and travel to Europe, which i should inform you is made up of lots of Countries, (27 member States of the EU). you will notice the following;
An English football game, you will not hear the National Anthem.
A Champions League game which is usually a club from one Country playing another Club from a different Country and guess what? No National Anthems!
Over 70`s lawn bowling, No Nationa Anthems! and so on....
Why? They know who the are.
The only time it is sung or played is at the Final.

This North American over the top patriotic crap is no different than that of North Korea or China. Lets be honest here, they do exactly the same thing, at every occassion possible they have to sing or listen to the Anthem, I call it brain washing!
I guess really that makes Canada & USA Communists in a certain way?.

Lets remember one key thing here folks, USA & Canada is made up of Immigrants, many like myself, who choose not to become a Citizen of the Country, why? I am here on my own accord. So why should i have to sing O`Canada at every sport event when a very large percentage of people attending are not Citizens.
Both Countries are so insecure of there identity and constantly feel that the more they ram it down your throat the more they believe it makes everyone feel better. NO! It`s painfull and laughable, seriously.
Take the Anthems out of everyday sports! There is no need for it.

I have now finished my Pasty, so my rant is over,
