Every fanbase has some, our fanbases are filled with them. It is a lot of goalpost moving, woe is me BS across all sports. Massive inferiority complexes that never let them enjoy anything. And it isn't the minority, and it isn't new either.
This thread is the perfect microcosm of Minnesota sports fandom. Team struggles, everyone climbs to the highest peak ready to jump if things dont turn around, team rebounds, fans say it isn't good enough and they still are gonna jump because what does this mean for the future and who cares the world sucks and we will never be [insert rival here] and our coach is too old/young/fun/boring/stupid/smart/fashionable...etc! Rinse repeat.
