Why does the January transfer window bring out the worst in fans?

Given the wave of pessimism and negativity that is currently seizing Charlton fans, it is interesting to read an article that claims that the January transfer window brings out the worst in fans generally: In the dumps in January

The article notes, 'Clubs are regularly criticised for what is perceived as lethargic inaction when they are actually endeavouring to complete deals behind the scenes. The disconnect between how much the fans know about the club’s inner workings causes friction and often leads to a toxic and fractious atmosphere online.'

'There is a collective suspicion among each fan base that their club will somehow be left behind and that a failure to sign a first-team regular (at the very least!) will derail the club’s season. [Sounds like Charlton]. Never mind, historically speaking, successful January signings are few and far between when it comes to significantly impacting the season in which they occur.'

Those forecasting relegation rarely refer to the points deductions heading the way of Birmingham City or Derby Country, nor to the limitations of teams like Luton Town and Wigan Athletic. You don't have to be great to survive, just a little bit better than the worst clubs.
