I'm going to have to ask you to elaborate if you intend to claim such things. All of those stages are fine.
There's NOTHING wrong with Japes, RC, Pictochat or Aero Dive, and the only problems with Brinstar and Norfair is that they are overly abused by MK. (and his planking, in Norfair's case)
Don't make blanket statements if you aren't willing to back them up.

WARNING: LARGE OFFTOPIC POST
Saying they should be legal is a much different thing than saying there's nothing wrong with them.
Japes: The stage layout really favors characters like Falco and (I believe) Peach in a lot of match-ups, and the water really favors Falco (CG into Spike) and Kirby (I believe). Maybe I'd be willing to bet if it wasn't for Falco this stage would be more legal, but I don't know. There are quite a bit of problems with it though (claptrap, water, approaching campers [mainly Falco], etc.).
RC: The moving itself isn't necessarily a problem because it's so predictable, but the shifting blastzones and more aerial-favored layout makes it dumb for some match-ups, gives MK a huge boost and others a good one as well (I believe Dedede does really well on it in most match-ups).
Pictochat: In my opinion, this should be a CP (along with RC), but again, it's not like there's nothing wrong with it. While you can react to the stage transformations before they come active, there's only a small pocket where you're 100% safe. The main part and most of the transformations are dominated by ground controlling characters like Falco, Diddy, and I believe Dedede, and while most of the transformations aren't bad in terms of interference, some are (the moving cart and the missiles, for example).
Aero Dive: The cars (and walls and floor, I think) punish too hard in Brawl. In Melee, getting hit by a car at like 70% didn't kill you or do 40% damage (probably over-exaggerations, but whatever). In my opinion, you shouldn't be punished that hard for messing up. The fact that there aren't ledges anywhere would make it a good CP if it wasn't for the cars, walls, and floors, but with all of those combined, I don't think it should be legal.
Brinstar: I thought Wario abused it just as well with his air-camping. I read somewhere that because of his aerial DI, if you get hit by lava, he can footstool you and keep a lava->footstool combo going until the lava drops.
Norfair: I thought the real reason that Atlantic North banned the stage originally was because Spammerer abused it as Jigglypuff. I heard the story from Thio, but apparently the priority of her Pound attack, combined with the positioning of the ledges, means that you really can't hit her when she gets the lead. Other characters that do really well on this stage (that aren't MK) are G&W and surprisingly Diddy. Not that MK isn't good on the stage, but from what I see and hear (mainly hear because Norfair's been banned everywhere), he's overrated, or at least rated as being the only really good character on the stage.
My ideal stage list (NOT RELATED LOL) would probably go
Starters:
Final Destination
Battlefield
Smashville
Yoshi's Island
Lylat Cruise
Counterpicks:
Pokemon Stadium 1
Pokemon Stadium 2
Castle Siege
Delfino Plaza
Frigate Orpheon
Pictochat
Jungle Japes
Rainbow Cruise
LOOK GUYS BRINSTAR IS BANNED
dunno why I just posted all that
edit: I thought the last backroom vote was almost 2/3rds anti-ban, not 2/3rds pro-ban.
edit2: @Jack, it's fine. You just got really upset lol.
