On most threads it's pretty much fine to just read the OP and then post, but on ones with a developing debate, it becomes irritating for the people who have already gone over the points that you bring up which have long since been proved redundant, because you didn't read it. I'm not trying to bash you, I'm simply saying that in a structured debate, you can't join in without knowing the stage that it is at. If I want to contribute my opinion, I will always read the material first so as not to re-hash any points that others have already made and have been soundly refuted. It's a waste of mine and everyone else's time.
Read through this thread, I'm not actively trying to start arguments, I'm posting in a thread which was made to be a subject of discussion and debate, and after posting my argument and the supporting evidence and reasoning, using a scientific method of removing as many variables as possible, I am now free to discuss any further points that people bring up.
