That sounds like an odd thing to do at a game!?!
Celebrating a republican country which rebelled against the Crown, killed British Soldiers and broke free?
Irony at it's best
How is that ironic? Rangers is a club full of different religions, races and nationalities. It is a recognised national holiday in the states, it was a bit of fun because of the US internationals we have at our club.
The Xmas tree originated in Germany. Do you find it ironic that's in nearly every house in the country at Xmas each year?
