It's a free country thankfully and people can choose to support who they like. There's Mags living in Sunderland and surrounding areas and there's Sunderland fans living in Newcastle and it's surrounding areas. I really can't see the issue with that and I think only someone with some sort of mental issues would tbh. I mean fancy getting wound up because someone supports a different team than you do
I'm from Peterlee and we have Mags living around here and there's plenty of them get in the club which makes for canny banter. At the end of the day we are all just football fans. You'll always get the odd (and I mean that literally) arsehole that will try to take things too far, as has been proven on here, but speaking from experience I'd say 99% from both sides are spot on. I wouldn't like to think that Lads fans living in and around Newcastle were getting a hard time just because of who they support, so likewise I wouldn't dream of giving any of the Mags around here any grief, other than good natured, either.
