I have ignored this thread for a while but I agree with the OP - the Union Jack Flag is not their own countries flag.
So as an Australian which is a Member of the Commonwealth, should I not have the Commonwealth Flag representing me? Or even the Union Jack, as we have the same queen?
The fundamental difference is they are not country flags, and those in the home nations should be treated in the same way - ie have their OWN flag shown.
In my eyes there is no excuse apart from laziness by the programmers at best, at worst it is pure ignorance.
I agree they are only flags and have no real meaning, but we did not ask for them, they are there whether you like it or not.
As already stated in this thread, having your home countries flag instead of a Generic British Flag has been asked for hundreds of times.
But as usual the rest of the world tend to get ignored, in courses (or lack of them), avatars (Nike), tournaments (virtually every special tourny) etc.
Some "World" Golf Tour, more like US Golf Tour - taggers on welcome.......occasionally.
