Tendmote, let me categorize possible positions about the social sciences for you.
Position 1: Social sciences are exactly like the hard sciences. Through research and experiments you can derive "laws of society" comparable to the laws of physics that you can use to exactly calculate what is going to happen next.
Position 2: There are no such things as "laws of society" and trying to find them is futile. However, using amongst other means statistical data gathering and analysis, you can still look for patterns and trends in the way society evolves. You can then combine these patterns and trends into a scientific theory that, although not as rigid as most theories in the hard sciences, is a useful tool to predict and analyze what effects certain events are more likely to have on society and what effects they are less likely to have.
Position 3: Social "science" is a misnomer. There is no way in which science can produce any useful insight about society.
Position 1 is the position that you, tendmote, seem to be arguing against all the time. It is a red herring though as no one in this thread has said that this is their position. Therefore your arguing against it is annoying, completely unproductive and most likely merely more inspired by your own politically biased agenda to discredit the social sciences than by any honest attempt of yours to make a useful contribution to the discussion.
Position 3 is the position that you, tendmote, seem to be taking yourself. It is a completely defeatist position that cannot in any way contribute to the furthering of our knowledge about society, because it simply doesn't accept the premise that such knowledge can be found or even exists. If this is really your position, well okay, I can't help your stupidity. However, rather than continually crying from the sideline "it can't be done!!!" to the people who are trying to do something, you might want to consider shutting the hell up and letting the people that have confidence in the possibility to actually acquire knowledge do their work.
Now, for any sane person (which obviously excludes tendmote so far) position 2 is the only reasonable position to take. If you too wish to join the sane, tendmote, you are welcome to do so. If you are in doubt of how to go about that... here's a suggestion: instead of just talking about how in your opinion we cannot gain knowledge about society, try explaining how in your opinion we can.
