I don't see anything wrong with the thread. There are just certain posters that shouldn't be allowed to take part in these discussions anymore.
Some people don't want to have civil discuss things. They want to win. They don't want to hear a different opinion. They want to be told their opinion is right. (I'll admit that at times I've fallen into this trap myself, but I like to think I've gotten better about backing off once I see where it's going.)
