Well, I mean, like it or not, they were. (It obviously fell by the wayside for about a century the second they realised there was cash to be made out of this football lark, but there's no denying their reasons for forming.)
When it comes to us, we were formed simply for a sheer love and passion for the game by young, ambitious and committed lads, who not only wanted to play football, but wanted to be the best - and they achieved it... and then some!
We had no political or religious affiliations for the first few decades of our existence, then became linked to the Orange Order and Loyalism after the arrival of shipyard workers from Belfast who attatched themselves to Rangers.
We've sang in support of loyalist paramilitaries - I ignore people who claim we're singing about the original UVF in the same way I ignore scumbags who claim they're singing about the original IRA - who also killed indiscriminately... including Protestants.
Yet we still draw support from that community.
Many of them are (rightly) proud of their Scottish heritage despite being born in NI, like generations before them. I'd imagine that's the case with that mob and their English born fans: they'll have Scottish or Irish ancestry.
