Hopefully it's all peaceful.
But you will get one or two who will let the green brigade down .
Sadly all clubs have them.
Not all clubs do and all the green brigade are ar#eholes. I have had experience of that mob in whites bar in Dundee
Al football clubs do have idiots the bigger the club the bigger the number .
Your experience may have been you telling them what you think .
My experience was having to leave nearly a whole pint when these ar@eholes came in and straight away started singing pro ira songs.
What a p ussy 😂.
All offended by a few songs, should have just finished yer pint
I think Deemo is on the wind up that's all . 
I think you are. "Celtic fans don't sing IRA songs" 😂😂😂😂😂
