You see, this is where I take issue. "Everybody" is a pretty conclusive word. From what I could see, there are people who dislike and like Diaz in equal measure. Same goes for Lesnar. Same goes for Sonnen. etc.
People tend to give far too much weight to the posts they disagree with, and not enough to the ones that do agree. So, in your case, you're left with this feeling that "everybody" is praising Diaz. But they aint bro. Far from it.
Sometimes you need to step back from your personal opinions and actually look at *all* the posts. You soon realise that just as many people agree with you as don't. To leave the forum because not everybody does agree is being a bit knee jerk.
Personally, I like this place a lot. I have NOBODY who lives near me who enjoys MMA. Without this place, I would have NOBODY to discuss it with. Seeing as its my favourite sport, I'm more than happy to take in all opinions. Its far better then no opinions at all.
That's only because the UFC hasn't expanded to the Moon yet. Once they start doing shows there, its popularity will pick up.
