I've been reading the last couple of pages to understand what this whole discussion is about. Right, so some people hate Barca because of their football style and philosophy; and other people think it's admirable and we should be doing the same.
Personally, I wouldn't get too hung up on how a team plays football now. Football is in constant transition and there isn't a single team in the world that plays the exact same football throughout its history. This whole Barca possession football is very recent, Inter I clearly remember used to be one of the most attacking sides in Europe; they were nothing like they were under Mourinho.
The point is, I think it's silly to assign one football philosophy to a team. It's managers and players who decide how a team will play its football; it's not like there's a Barcelona philosophy book that has -) Play possession football as their 5th rule.
Regardless of a team's playing style because I think that's entirely subjective, You're perfectly free to like Livorno's playing style over Arsenal's, I don't see how people can look at me with a straight face and say, "Xavi, Messi, Iniesta are not world class players that are one of the best in the game."
It's not like I enjoy admitting it. It really pains me to say this, but they play great football. I appreciate the talent it takes to maintain the possession over such long periods in the match so seamlessly, and I also appreciate the team's ability to boss around Mourinho's Real Madrid like they were a bunch of lost preschoolers.
It's hard to be a football and not recognize the quality this Barca team possesses, unfortunately.
