It seems as if animosity and rivalry with clubs has lowered

I'm basing this on what I've heard from family and a bit of my own grey matter (I'm a teenager so I havnt exactly got experience of old football etc ).

But it seems that animosity between the 3 main north east clubs (Newcastle, Sunderland, Middlesbrough) has lessened, )

Especially if u compare now and the 90s , my guess is it's because we've not had consistent matches between boro and Sunderland. But also fans seem more hostile to Brighton and man u than anyone else .

I know about the 60s-70s where people would go to the Newcastle game one week and go to the Sunderland game the next
