I do agree with you about the fans behavior, although this was just a small section of youths on the townend i heard who be to totally fair probably attend these games half a dozen times a year. Although there was also a few i spotted who should know better been regulars. It really was embarrassing, hearing shouts towards our players of " your crap " and " we're going down " etc. As true fans, we can only stand up them and tell them what idiotic kids they are being.
As for the referee's abuse, to be honest it was warranted as he was awful and gave nothing from the sure fire red card that wasn't to some clear handballs and fouls. But to abuse your very own team is what sickens me !
Regarding your questioning of work rate through 90mins, i find that harsh to be honest as i have seen this team run its legs off on plenty of games last season and they always give it their all. Every player, in every team will make a stray pass during the 90mins, or make a mistake. Even in the Prem !
