You have absolutely nothing to apologize for. By all accounts you’ve proven to be a very passionate Cyclone fan. Posting something negative or pessimistic (or hell, something factual that may not reflect well on our team, like a nasty stat or analytic) in a game thread is …quite literally what message boards (particularly free/anonymous/sports message boards) exist for. This is a safe space for fans to cheer AND vent - together, all the same time, day after day, game after game. Respectfully of course, and you’ve never crossed that line.
Nothing more annoying than the army of holier-than-thous that make it their life mission on free message boards to crush passionate fans for expressing emotion and opinions, as if these emotions and opinions are somehow evil or illegal or unnatural or wrong, or in any way affect their well-being/quality of life or the well-being/quality of life of any player, coach, or employee of Iowa State university.
PS. If someone here does not care to be around perceived negativity or pessimism or frustration - - or strongly does not agree for example of another poster claiming to be concerned to see the 2022-2023 Cyclones demonstrate an unfortunate trend on the road where late leads seem to collapse - there’s nothing wrong with that either! Perhaps consider blocking them?
