You're either born here or your family are from here. That will do for me regards support. We have a massive fanbase because of this and it does get passed down, I am proof, Family are all born in glasgow, aunts, uncles, cousins etc aside from me and my sister never changed or indeed was even a question of changing team despite us both growing up in England. Went to Ibrox first time with my dad and uncles etc when up on a visit never thought of following anyone else ever, and would not have been allowed to anyway! Don't go anywhere near enough now but seriously Rangers are my no.1 focus which looking back on that looks obsessive but heh that's the way it has been for a good 30 + years!
