Not often I don't agree with you E I Addio but I do here.
I have given the matter some thought as you put it. As a result of those thoughts I believe that the 'TeamGB' name is inappropriate. Great Britain was good enough for years but, in order to become 'fashionable', we change our National Team's name. Oddly enough, I live in a Country called Great Britain as do most on this Forum, nowhere can I find the word 'Team' mentioned. Our Speedway Team, and other Sporting Teams as well, are supposed to be representing our Country, our National Identity if you like, hence my reference to the Flag in my original Post. Ergo I believe Great Britain to be the correct name for our Speedway Team.
Now I know from what you have Posted that you do not agree with me, that is your opinion and your privilege. I also have the right to disagree with you in this instance - and I do.
Hoping I don't get the unnecessary heart attack you mention.
