OK So someone may NOT have been a fan in the 1970s or 80s however they could be now then??, since that same fan with the same activity whether its "scrapping" or abuse messages or whatever, could be done decades apart. Yet the fact is in the 70s and 80s there were many reasons why people did not go to football compared to these days . Not least economic factors like union strikes, financial hardhsip, 3 day week etc . Less media attention than there is now. Whereas now footy is a glory sport, funded heavily by Sky tv. completely 2 different eras and many many different factors behind it . Can't blame it all on lads who were hoolies.
That same fan might 30 years later still be , you use YOUR words " supporting the club's efforts to achieve success" and doing the same activities whatever they were/are.
as i say it doesn't make them LESS of a fan . In fact from my own experience and people i have known over the years often those sort of fans spend much more of their disposable income on SUFC than the so called "plastics". Thus considering that you could argue they are MORE of a fan as they are financially supporting the clubs efforts more than others....
Does this person whoever made these comments on the social media overnight night become a "non fan" ? Its the club/media who portray this "so called" image of who they perceive is not acceptable to THEM
