I 100% agree, but I think the problem is bigger than just 1 person. There's a good deal of people across the community (the forums, the subreddit, Discord servers, etc.) that are very much stigmatizing and hostile towards people who give even an ounce of criticism. It's always just retorts like "stop being negative!", "you're ruining it for others!", and "let others be happy!". While these statements may have good intentions, the end result is fostering a clique that becomes so ultra-positive that it's outright toxic.You are not the only one in the forum constantly misusing the term, though. It's a desease these days, now that it is a trend term and misinformation is spread around like crazy.
And you know I appreciate you a lot. I really do. But is indeed a "you" problem. And I am not saying that in a dismissive way. But you are framing concerns and frustration of others as "negativity", completely ignoring that even critisism and concerns grow out of the love for the game and out of the reason to wanting PZ and down the line PZ2 to succeed. Besides that, I have absolutely rarely seen anyone hating on the WHOLE pack. It is always accompanied by "okay, I love this and that addition". So you really have to ask yourself: Why is YOUR focus on the "negativity" and not on the appreciative and acknowledging part?
I am not saying it is the case with you, but sometimes people are afraid of the "negativity" of others, because they have subtile concerns of the direction things are heading as well but try to surpress them or gloss over them, Very rarely get people who are TRULY okay with everything going on get triggered by others opinion.
That said: In any community there should be room for pure happyness and satisfaction and for frustration and concerns (if not proposed in a trolling manner). No side should be made silenced just because the other side might feel annyoed or uncomfortable. Which is why I would never qupte anyone who is 100% happy with the pack and ask: "You are truely happy with another sheep?! How can you not see we already paid for sheeps three times in a row!"
Are there bad ways to frame criticism? Yes, of course! If you're pointing fingers at people and saying they aren't allowed to enjoy this, that's a poor way to get your ideals across. Going to the root of the problem is far more effective at getting the message across without meltdowns. But it becomes a glaring double-standard if people chastise negative commentators who point fingers but completely endorse positive commentators who also point fingers. If you're going to judge others for their behaviour, your judgement should at least be consistent regardless of how much their views align with yours.
