You said 4e fans are superior to everyone else
Superior? Different. Willing to adopt the new can be seen as positive or negative, depending on your PoV, but it's certainly different from defending the old.
Edit: But, hey, if thinking of yourself as superior matters so to you, you can always spin it hard in the negative direction, something like: former 4e fans must be a bunch of uncritical WotC apologists who automatically adopt the next edition no matter what it's actually like. That better? It's rooted in the same phenomenon - a surprising fraction of current 5e fans calling out 4e as their alternate-favorite edition.
Hope that helps you deal...
Thing is, time has marched on, and 5e is new. That many of those longtime players who are now 5e fans also adopted 4e in its day should hardly be surprising.
And, to be fair, "everyone else" isnt the main contrast being drawn - as the playtest era, presumably more-scientific polling concluded,
most of the fanbase has no strong edition preference. Rather, it's between former 2e and 4e fans now playing 5e, and continuing old-school and 3.x fans not doing so. (though, hey, look, 3e has totally taken off in the poll, now that the thread's seen a little edition skirmishing)
I mean for Christ’s sake, how many threads has CapnZapp alone made in the past few years attacking 5e?
I couldn't say, I've argued with him a lot, certainly, and he's easily one of the most 5e-critical regulars here. But it's not like he's boosting 4e, he's very often looking for more 3.x-isms in 5e. Celtavian would be another example of a resident 5e critic, and his main complaint is that 5e isn't hard enough.
But they're lone guerillas compared to the legions that marched against 4e in the edition war.
Just look at any warlord thread that is still going on today.
Though they've proven futile, the point of them is to get a decent, official, Warlord in 5e - not warring against 5e.
