Genuinely speaking, some of my favorite posters are ones I often disagree with. I think you can have civil discussion and disagreement.
I think having different perspectives is important.
I don’t think that’s really a fair comparison. If I’m out at a bar (which to be frank, I’m usually not haha) or outside, I’m usually minding my own business or enjoying my time with friends. Perhaps if someone is attracting a bunch of attention or I think of something witty I could interject with, I might join in if I’m in the mood to do so. That’s actually part of the appeal for a lot of people with the bar example, which is meeting and chatting with people who may be total strangers.
This however is a public forum meant for discourse on various topics. When you post, it’s expected that others will interject with their own thoughts. That can vary from threads where players are asking for advice, discussion posts about the game, etc. It’s the norm to chat with people. I don’t think there’s anything rude about that, the setting encourages it by design.
I genuinely enjoy reading posts by players like Mawthorne for instance. While I think we have plenty of things we may not agree on, I think he is calm and often rational in his thought process, even if I may disagree with his conclusion.
