That's a very, very, very good question, Woodbinebhoy. For as long as I've been a Celtic supporter (only a couple of years, mind you, and from 5,000 miles away in California), it appears that many fans are never happy and always have something to complain about. Always. You are right -- this season, like a lot of things which are a product of 2020, things are upside down and we may not end up winning the league this year, but as long as the math is there, there is hope. But after winning a quadruple treble, which will probably never be repeated, that crowned Celtic's recent string of successes, some consider the club a failure.
I support Celtic first and foremost, then there's about 50 feet of dead space, and then I also support two other clubs: FC St Pauli and, here at home, Portland Timbers FC in the MLS (I'm a member of the Timbers Army, the PTFC ultras). The fan dynamic in both of those clubs is much different than Celtic, insofar as when crises arise -- and especially in FC St Pauli's case, where they are staring relegation squarely in the face unless they turn things around -- there is never the level of negativity or vitriol against those clubs at the level that manifests itself when Celtic stumbles and some Celtic fans shift into entitlement overdrive.
Let me be clear: Many, possibly most, people who support Celtic know that "faithful through and through" are not just four random words, but a solid foundation of supporting the club. But apparently the loudest critics -- whether in this forum, on social media, or in the mainstream press and broadcast media -- are an embarrassment more times than not.
Oh, and welcome to the Noise.
