I've heard more whining than optimism. 
Boundless homerism is annoying too, but I can't say I've seen much of that so far.
I don't think you're quite getting the spirit of the gameday threads - my understanding of them is that they're best seen as expressions of the WNFF fans collective id - no reason, little thought, mostly just emotion-filled tirades. Which is why, when the offense is offensive for fully 22 out of 27 innings that have been played so far, you get a lot of death threats, whining, snap judgements, etc.
Outside of that - sure LaRoche has looked good for two games which seem to match his previous level of non-injured production. Nevertheless, the guy is beginning his age-33 season and coming off a major injury. No, he may not be as bad as he was last year, but it's going to take more than two games after a turrible game for me to say "Yup, pencil him in for 25HR, 100 RBI and a .480 SLG."
