Great post, there's a few camps that form every time anything like this happens. If anyone gives feedback at all, they're called bedwetters by the other camp. That camp decides they're the real supporters and we see many instances of the "no true Scotsman" fallacy. They will say that people actually want us to lose so that they can complain, and the second we win a league game they'll be pointing out how we've turned a corner and the bedwetters were wrong etc.
The truth is you can point out obvious failings without being a crap fan or a bedwetter and if you can't spot areas for improvements in these games you're just being a cheerleader / fluffer for the club, giving blind faith. It's normal to want to be better than bottom of the league.
