It's hard to agree to disagree with an issue like this because it means that things won't change. Some people here have argued that the current state of parsers is fine because people who benefit from parsers are already using them, but like Whiteroom pointed out (and the anti-parser crowd has conveniently not replied to this), this is purely false because console players do not have a means of using parsers. I don't want to be a burden to my PC friends every time I tweak my rotation and cooldown usage to see which one gives me better damage over time or more burst. I'd like to see how much damage I can do over a 2 minute span on my BLM compared to my DRG or NIN. These are all things I cannot do by myself, and I enjoy bettering myself as a player and constantly pushing myself to do more damage because that is one of the ways that I have fun playing this game.
Also, I've asked this question in other threads and still no answer has been given. Suppose that you are PFing Bismarck EX (I'll use this as an example as it's an infinitely easier check that anything Alex Savage has to offer, and is more accessible to the entire player-base than AS). You are not meeting DPS checks and you keep wiping. After four attempts and dying at the same part of the fight, you can either disband the whole group, or actually deal with the problem and kick the one or two players who were not performing up to par. Why is it easier to wish to remain willfully ignorant of what's going on instead of dealing with the problem? Why are people so insistent on barking out a healer or tank who are causing wipes, but remove all responsibilities from DPS players?
As a sidenote, no one is arguing about values in the communities. Many people have different reasons for playing this game, and that will never change. You have players who play mostly for the social aspect, you have others that play to rise to the challenge of this game's hardest content, you have those that vaule crafting over everything else, and others have a combination of the things stated above, or other factors I didn't mention. In that aspect, of course, there is no "right" way to play this game. BUT, if you choose to enter a fight, and your chosen playstyle is keeping a group from clearing (as the worst example), or you are pushing 300-500 DPS in a dungeon where other players have to perform better in order to make up for your lack of damage, then the group reserves every right to kick you.
