Who thinks it is right to sing the national anthem at North American Sports?

Question

I come from Scotland, and am just wondering what people think from the U.S. and Canada, and abroad, think of the fact that before every sporting event, the players and fans have to stand to the National Anthem of the Team i.e. Green Bay(US), Oilers (Canada). Though I have been to a few baseball games in both countries, and I did stand, silently, respecting the traditions and both National Anthems, I was wondering on the views of the Canadian and U.S. population on this, due to the fact many teams, at least in hockey and Canadian football, have foreign players. I also heard this was the same at the start of the day in school (at least in Canada), where many foreign persons may be attending, and are they forced to stand at this point?
In the UK we only stand to the national anthem when Nations are playing against each other at Some sport, ie football(soccer) or rugby.

Id like to point out that im not complaining about it in any way, but am just curious.

Please say about the start of school and what u think, if this is true about the national anthem.

Answer 1

It is our countries tradition. And I am proud of it. If more than one country is completeing than that should be the other countries choice to also sing their anthem. I love the good ol USA!!!!!

Answer 2

if i were in your country and they played your national anthem i would stand and be quite, whats so hard about that?

Answer 3

I understand that it started in the U.S. during the first world war.
