I still don't understand the premise for the thread! if threads bore/upset you, don't read or answer them. unless, of course, you feel you have some right, to dictate what people think/say. and, as we don't have that right, it still makes no sense.
This is just me, but for some reason I love to complain and love to hear other people complain. I love to look at negative reviews of books and movies (Even if it's something I love). I can't explain why I like it, I just do. I don't really want people to stop doing all of these things, because at that rate we wouldn't have a forum.
Likewise, I could ask why you're bothering to read and reply to this topic if you don't like it/agree with it. But here you are! Its fun to discuss things. Maybe we need a sister topic like "In General, What Type Of Posts Do You Love?"
