national anthem

I get it now, thanks.

How is this discussion even occuring?
Why do we sing the anthem before a hockey game? Why WOULDN'T we?!?
We live in a country that provides us with the freedom, availability, money and safety required to let 17 to 60 thousand of us attend these games at a time.
I think that qualifies as 'just cause' to belt out your nation's anthem and show your patriotic lets you remember how great the country you live in must be that you can attend such events.

Why the US sings their anthem before games...I don't know. Helps with the Army recruiting going on in the concourse I guess.
