Does anyone have a good explanation for this?
Yes. I don't think
criticising 4E is dog-piled upon, as long as the criticism is well-founded. Same is probably true for liking 4E.
But now enter non-reasoned hate or love of 4E:
"I love 4E" - it's an empty message. No value whatsoever, you simply gloss over it.
"I hate 4E" - similar to the one above, but it contains negativity, which in turn can be disrupting.
And if we get into full-fledged flaming, it gets worse: If you take "I love 4E" to the extreme, you get "4E is the best game ever and everybody should play it!" - but if you take "I hate 4E" to the extreme, you get "4E is the worst game ever and nobody should play it". But since the second statement already contains a lot of negativity, it's much easier to slide into "everybody who plays it is dumb", because you're already negative.
If you, however, positive, you're less inclined to produce negativity in form of personal attacks.
So, from a point of view of a moderator, who is inclined to keep the board civil, it's better to keep an extra eye on 4E-hate, because it is a topic that slides into personal attacks very easily, hence you also get more negativity from other posters (which, in turn, gets people on both sides suspended, I've seen a few pro-4E's suspended for a while).
Well-reasoned criticism however, is an entirely different matter.
Furthermore, ENWorld was always a board for D&D, but more specifically for 3E. I daresay that people who dislike 4E, because it's a departure from classic D&D, are already (at least partially) disliking 3E, hence there are less of them here, so there are more posters on the pro-4E side, hence the impression of dog-piling.
At least that's my observation of that matter. I guess it's rather the first aspect than the latter.
