Think you are missing the point mate. I want United to win as badly as anybody, but I am critical of the people who go to the extreme every single time. Calling players a disgrace because they had a bad game, criticising players for celebrating goals, hoping we lose so the manager gets the sack.
All of those things, in my opinion, are childish, over the top, and actually, more importantly, my point is really if you stop getting so wound up about it and just take the good with the bad, you will enjoy it far more, which is what it's supposed to be about.
I don't care what you think of my "mentality" with regards United. I look after the things in my life I can control. I can't control what United do, who they buy, how they play, who the manager is...following United is a hobby, a recreational activity.
Tell you another thing as well...its too much media/news and round the clock coverage that is winding people up. It's designed to keep you angry, to keep you watching/clicking. Just turn it off.
