I think that Celtavian brought it on himself a little bit, with the melodramatic tone of his post. From the title of the post to him telling people not to argue with him, that's just flamebait plain and simple. If you want to reduce edition war threads, you've got to put a stop to flamebait as well as flamers.
The problem is, "flamebait" is now defined as "Saying anything bad about 4e." Furthemore, he never said "I'm right, don't argue with me." What he said was "This is my opinion, I played the game, you really aren't going to change it. I've had a lot of experience in D&D, and yes, I've had a lot of experience with 4e. This is how I, personally, feel. You can't force be to change my feelings on this."
Cue dozens trying to do just that, in some of the most insulting ways imaginable.
As for EN World having a big part to play with 4e, I'll throw this out - before 4e officially came out, if you looked up 4e info, EN World was always the first place that popped up. Even when Wizards was throwing out their tidbits and design philosophies, it wasn't wizards and that tidbit you'd find, it was EN World linking to it. Claiming it had nothing to do with the edition launch is laughably and purposefully ignorant.
