I can tell you all, from seeing them both MANY times whether it be at ibrox, park head or Easter road, they both have their very disgusting inhuman sectarian vile people within their support.
I'd say with about 40-50% of park head being 'Irish' there comes a lot of unrest around Remembrance Day. However the rangers fans are in your face with their loyalist and pro British nonsense. I'll also say so many of both support don't have a clue or any actual ties with the rubbish they spout and sing about. It is certainly not any worse or better from either side. They are both two cheeks of a very smelly big and horrible arsehole.
That's from what I have been subject to and I've seen and heard at both their grounds. And with many travelling from the east to watch them both we are all subject to their nonsense. It occurs all over Scotland.
