Then maybe you need to go to convention or game store or something.
Two conventions a year. Encounters every Wed since the 2nd season.
Heck, I could say, "I haven't heard anything from D&D players other than 4e is a horrible game."
You can say whatever you want, really. I wouldn't be surprised if you had said something very like that, back in 2008 or so, you might even have carefully avoided talking to anyone who had played 4e, just be sure it'd be true. Or not, no one can check up on you.
I mean, I don't go out and talk to 4e fans and they don't talk to me, and the people I have talked to are people usually in the same circle I am who don't like it.
Yeah, I still play 3.5 now and then (ironically, perhaps, in preference to 5e, while I happily run 5e, and wouldn't run 3.5 again on a bet), there's PF games at my FLGS, I have friends who can't stop telling me how awesome it is (and it certainly has a few good points), I actually do get to talk with a variety of gamers IRL.
It's not even a dig at 5e, exactly - that 5e managed not to set off 3.5/PF hold-outs the way 4e did is still not a trivial accomplishment. It's just a recognition that a lot of people don't acknowledge it as bestestedevar the way some on-line enthusiasts do. Each edition still has it's fans who find it better than 5e. Reviews often say "best editions since _____" which is a nice way of saying 'second-best,' when you think about it. But, it's good /enough/ to bring a lot of those folks together, while pushing the whole 'bestest' button is only going to antagonize them.
Conversations like these make me realize how easily it could have gone sideways, too. I mean, it wouldn't have taken a lot more 'tude than we've see in some of the threads here to hit a tipping point and ignite another edition war. I'd hope that, a year and a half in, though, we're past worrying about that sort of thing...
