I agree with you, to an extent
I've visited here regularly for about 2½ years.
I started out SUPER toxic, I couldn't sympathize with anyone. But now I'm actively trying my hardest to not do that anymore. I try to empathize and explain rationally how the system works.
But a lot of other people seemingly don't do that. Over the years, very few regulars have stuck out to me as not being rude, and a few of them even began transitioning to being toxic.
I guess the simplest explanation is that the regulars get into discussions that turn sour. When a new thread appears, they can't separate their previous heated discussions from new ones. Their default becomes toxic over time.
On PB we've made kind of a culture. It's no longer really about helping those who come with questions, but about garnering upvotes and respect from your PB friends. The culture is ingrained deeply. I even feel some of the mods have this. They post snarky comments that are unhelpful and in some cases will turn away people from asking questions in the future..
HOWEVER, I don't think we should remove PB. I don't like how loosely moderated the forum is. I understand that they're volunteers and human, and make mistakes. But I feel like they don't even try to be examples of how a good regular should be.
But this doesn't mean PB is useless. Sometimes good things come from PB. Players have interesting discussions, or someone gets a proper explanation which they're thankful for. Even through the years and the toxic times of me being here, the most memorable moments have always been when I've helped someone and they thanked me. Likewise, I really have taken note of when someone actually managed to make me see the picture through their eyes.
The few good moments heavily outweigh the bad. Of course, that's just my opinion and all. These good moments come more often when no one is super upset, which is why I'm now no actively trying to be positive.
I'm sorry if this was hard to read, I just wanted to write my thoughts. I didn't really organize them that well.
