I think there's an international difference in the way people express themselves. Americans often come right out and say what they mean as forcefully as they like. Sometimes it sounds rude but isn't meant to be. Sometimes it sounds rude and it is meant to be but it doesn't mean what it would mean if someone of another nationality said the same thing.
Or that's how I came to understand it anyway. We English tend to be a bit more reticent. Some other nationalities bend over backwards to be scrupulously polite and not to offend, but sometimes they don't really say what they mean, so you don't quite know what they're thinking.
I've found this message board to be very caring, on the whole, and often very witty and funny too. I like it very much. It's helped me. Once or twice I've wandered into a situation and said what I've thought and discovered too late that there's a longstanding situation between people of which I was totally unaware. On those occasions, one in particular, the wisest course seemed to be silence. Personally, I don't choose to offend people, but I value very much my right to say what I think and the same is so for other people too.
I'd much rather have people say what they think than be afraid to express themselves fully, especially on a forum like this when people can help and be helped, and have fun at the same time.
So, no complaints from me! And I agree with much that's written above, especially from Flipper, Mad Sweeney and Talesin.
