Well some people will argue with whatever is said simply for the sake of arguing. If you say the sky is blue and you have boatloads of science and personal experience backing you up, someone will still jump in and insist the sky is yellow and have nothing to back the opinion except that they feel it is true and therefore it is true. Someone else will be a nitpicker and say that it's not actually blue but turquoise and gets mad that you generalized. Then someone else is going to jump in wondering about why people arguing about the sky has gone on for 27 pages of posts and that the whole thing is ridiculous in which case people get mad and start posting about how they can post about the sky if they want to and if the sky-hater doesn't like it, they can stop reading the thread, which will go on for another 14 or 15 pages of posts eventually getting to the point where someone else begins complaining about the thread being off-topic and another person telling that person that they are being off-topic for complaining about others being off topic. In the meantime one or two others start announcing how horrible people are in the thread which will obviously mean that others will object and go on for 47 pages of posts about how wonderful people are and how it's the best place ever and that their ancestors felt the same when they were alive. Then of course someone naturally declares that they agree with the OP that the sky is blue, which starts everything all over again from the beginning!
(Now i haven't been on this forum long enough to know if this cycle happens regularly here, but it seems to be fairly common with forums in general.
