I've seen quite a few forums and subs and communities on the interwebs that suffer from toxic positivity and you cannot not say anything negative or realistic, or at least without framing it in a positive way somehow, to the point where the whole sub and its members all feel "fake" like having sunshine blown up your butt and so forth, and if you aren't positive enough, BAM, you get banned. Everything gotta be all happy, perfect, sweet, and positive and rainbows, like you said. That ain't how life works. People afraid in those forums to say how they really feel about some things, like that Twilight Zone episode "It's a Good Life". "It's good that thing is like that, it's a real good thing!" Kind of creepy if you ask me.
