1) Team performance has very little correlation to what the fans do or do not believe. "Support your team" is a great concept but the team falling short in the playoffs isn't from a lack of fan belief or support and we can't push them over the hump with our own sheer will.
2) Like it or not, paragraph structure is important to the readability of a post to your audience.
3) Seems like you're a passionate Brewer fan and supportive of the organization, which is awesome. Yet when you got some pushback on things you resorted to personal insults, accusing others of being Cub fans, etc. Not so awesome.
