I've had 3 or 4 complete weirdos stalking me throughout the forum for almost 1 year now doing it. It's bizarre behaviour tbh and the mark of someone who goes to every match on supporters club busses.
Actually come to think about it you're right. Same reason they celebrate armed forces day as a thinly veiled "get it up you" to Celtic, not because it's something they actually stand for.
Once the queen goes the whole things going to come tumbling down.
I'm actually quite hopeful it will at least slightly dampen the spirits of unionism and bigotry in Rangers fans. Can't see them getting behind King Charlie quite the same.
