First, I will agree with the OP. Ret does feel more like a support role than a "pure" dps class. The thing is, though, ret paladins are not a pure dps class. Blizzard has stated on many occasions that "pure" dps classes will almost always beat out the "multi-roll" classes. It's a fact. If you can't handle that, reroll a "pure" dps class. If you can, then welcome to Cataclysm, we are glad to have you.
Second, and I will most certainly accept and cherish a ban for this, should a moderator act like this? Is this alright with the powers-that-be of MMO-Champion? I certainly hope not, because if so, these forum users will take a cue from this and make it worse for other good moderators. In my opinion, this guy needs to be outed from his responsibility.
