But, there is a pretty understandable reason for it. Actually, there are several understandable reasons for it.
Right before the announcement of 4e, you had the reaction to the ending of the print versions of Dungeon and Dragon. People went off the deep end for a bit, and then Gen Con hit and we learned of 4e. Even before we knew anything about 4e, people were massively over reacting. Heck, there's a few names that used to be common around here *cough Razz cough* that exploded into spontaneous nuclear flames right after the announcement.
So, it's not surprising that there might be a fairly equal and opposite reaction.
Also, there are more than a few criticisms that have been leveled at 4e that were basically rehashes of the criticisms we saw for EIGHT YEARS over 3e. Heck, you STILL see people claiming that 3e isn't really D&D. It's too [insert whatever term you like here] got chucked around pretty constantly.
So yeah, people got very, very defensive. And, people are still defensive about it. Because, you still see post after post of people claiming that 4e isn't "real" D&D. Heck, earlier in this thread people are claiming it's not even a fantasy role playing game. Add to that claims that it's an "inferior" product (also claimed in this thread) and do you honestly not see why people come out swinging constantly?
Think of how insulting it would be to a fan of any hobby to be told that the thing that he or she likes/enjoys isn't even really what he claims it to be. "Oh, yeah, it's not like a SS is a real muscle car, it's just a cheap knock off wannabe"
This is how I see it. The few times I failed my own will save and starting frothing at the mouth have always been in reaction to some chucklehead being insulting towards fans of the new edition. Doesn't excuse the times I've overreacted myself, but my own diatribes have always been in reaction to rude anti-4e folk. I've also noticed this behavior in some other posters as well, they are calm and rational until provoked with the ignorance and snark of a hater. My blood pressure still rises a bit when certain *ahem* posters post at all as they have insulting and inaccurate comparisons of the various editions in their sigs.
I've never seen a 4e fan START a flamewar (throw more fuel on the fire, oh yes). I'm sure it's happened, and maybe my own biases have gotten me to "not see" it when it happens, but that is my experience.
To try and get back to the thread topic, while I do think that many who are not fans of 4e have valid and honest criticisms and problems with the game (and post here accordingly) . . . the most vocal 4e detractors tend to have irrational and inaccurate beefs with the edition. And while anyone is free to like or dislike 4e for whatever reason they wish, I do think in large part this is a classic example of resistance to change that has little to do with the change itself (4e).
