I was a child of the 90's and whilst 2012 was awful, and what followed in our return to the top league and regular batterings was just as bad, it's not scarred me mentally. It hasn't affected who I am as a person day to day. I remember after the 2019 league cup final it seemed different, I was in an almighty huff and whilst lasted a few days it didn't affect my outlook on life or who I am for any longer than that.
Meanwhile, a substantial majority of Celtic fans I know that are a similar age are deranged and have been affected big time. Don't get me wrong it's not all of them, but I know a lot of Celtic fans who will take an almighty chip on their shoulder due to our 9iar, their coca cola cup defeat, helicopter Sunday, Arteta's penalty and so on to their grave.
I think it's partly due to not only their footballing failures, but their completely odd club supporter mentality of virtue signalling, a weird obsession with needing to be loved by the 99% of other football fans who genuinely couldn't give a shit about Celtic. And their need to be seen as some socialist haven of a soup kitchen football club when in reality their just a money driven PLC.
It would make a cracking case study for someone who has the required expertise. I'm just glad I'm not one of them as carrying that chip and constantly harbouring a victim mentality looks genuinely exhausting, I pity a lot of their too far gone fans.
