Where I see the clashes here is when people really want to express their Ideas, points of view, or complaint, they are not being open to counter views. Counter views balance out an argument. You might have overlooked a detail, you might be totally incorrect, you might not have experience with what you are suggesting or complaining about. Now, everyone be it an hour 1 player to head staff have something to contribute to Sindome. It is like life, everyone brings something different to a group. We have players posting who have been here 1-3 years, 3-5 years, 5-10, years, even 10-15+ years and all of them have a unique view of a slice of sindome. It is a good idea to hear why you might not be correct on something or why you may want to consider something else.^ This says it all, thanks Grizzly.
If I could describe what I see happening that's causing people to get salty, it would be to say that we have a number of newer players (like, less than year of experience) who post ideas and then get very defensive, sometimes militantly defensive, when other players point out counter-arguments to their suggestion or try to give them advice on how to solve the issues they're having via IC means/making playstyle changes.
I've gotten the sense this defensiveness might be a reaction to perceived snarkiness on the part of people putting their two chy in, or being told that because they're new to the game their opinion hasn't been colored by the same experience as more seasoned players (which can easily sound like, you're new so your opinion doesn't matter).
Meanwhile the more experienced players trying to provide counter-arguments and point people in what they see as the right direction are likely getting frustrated at their time/energy being outright dismissed by the defensiveness of the original posters, causing them to up their own saltiness.
So! With that it mind, a few more things to consider/remember:
1. Lots of things on the ideas board do make it into the game. If people are providing counter-arguments, it's not to attack -you-, the poster. It's because they have concerns about your idea or wouldn't want to see it implemented in the form you've described and they want to add their voice to the equation, which is completely their right.
2. As Grizzly said, no matter who you are, from Mix Legend to day one immy, we should all remember that other people/other perspectives are capable of having valid points. None of us knows everything or is aware of everything. Even senior admin who know every in and out of the game don't always know how each individual feature is being played in the wild, which is why they source lots of opinions.
3. As soon as you attack someone, you kind of throw your argument out the window. That's all they'll see, and it may be all everyone else sees, too.
4. There's no one metric every idea gets judged by. You'll see people make arguments for realism, other people make arguments for game balance, other people make arguments for fun. I'm pretty sure ideas have been included in the game for all these reasons. There will be internal contradictions to all of them, as well. Some things in the game aren't realistic, other things aren't balanced (eg, not every skill is equally useful), other things aren't fun.
5. Perhaps most importantly, everyone is entitled to their opinion. I feel like most of the aggression we see is ultimately a response to people feeling like what they say/think isn't being valued. But like, just because someone doesn't agree with you doesn't mean what you're offering isn't valued, it just means everyone has their own opinion, they don't always match, and the forums are specifically a place where opinions that don't match are going to come into contact with each other, so it's incumbent on everyone to be in a healthy mindset for that.
