If people would simply post in the way they feel comfortable on threads and stop complaining about how OTHER people post, it would be a different board altogether. Every week there's another thread about how people SHOULD post. And it doesn't help in any way. People are going to say what they want to say, and in the way they want to say it. I'd advise that people should block, but that doesn't do any good, either. If you block, people get upset. If you speak, people get mad. It's a losing battle, no matter what you do.
And to answer the question, "Can't we all just get along?" I'd say, "Probably not." But that's OK. We don't need to all 'get along.' There will always be people who agree with you... or agree with the person you DON'T agree with. It's a waste of time and energy to try to get everyone to 'get along.' And your comment about how "not everyone will have problems like you..." the same thing goes for the people who have had NO problems. If a prospective bandster sees nothing BUT happy stories, they're going to be in a world of hurt if they do experience problems. (And the band has a much higher incidence of complications, so the likelihood is greater.) There are always going to be those of us who have nothing good to say about the band and there are always going to be people who have nothing BUT good to say about it. It doesn't mean one's right and the other's wrong. It just is how it is. At the end of the day, you just need to be able to say, "Well, I'm fine today" if you're fine... and if you're NOT fine, you should be able to divulge that, as well.
So, post the way you want to... and say what you want to say... and don't worry about how it's perceived. Chances are, if you post to the people you have a lot in common with and just learn to ignore the stuff you don't like, you'll have a more pleasant experience. It's the numerous threads that are posted in order to complain about how others communicate their thoughts that cause the most discord, in my opinion. We're never ALL in a good mood at the same time, us humans.
