I don't ever recall seeing any remotely pro Irish flags at Tannadice in the sixties seventies or eighties but the Union flag was seen in abundance at Dens during those decades. Yet Sevco and (some) Dees fans have the cheek to play the Irish card against our club.
It's typical of the mentality of sectarian bullies. Maybe I shouldn't be surprised about it after all these years, but you live in hope that people will begin to educate themselves if no one else will.
Sadly when you read on messageboards references to taigs it looks like nothing much has changed.

If there's a sectarian club in Dundee it's certainly not Dundee United.
