From the link in the OP:
skeptism is not the same as reinforcing the official storyline.
Correct, its about looking at the evidence, which is nearly always absent on conspiracy theory sites (eg. Infowars). Skepticism (or scepticism) is not about the official storyline, neither is it about trying to make the evidence fit a narrative, as conspiracy theorists do. If you can't put up the evidence, your conspiracy theory falls down, as it does repeatedly (eg. Moon landing hoax, MMR, 9/11 Truthers, ....)
Also, many of the ones in the link are not even conspiracies.
Of those that are (such as Watergate), show how unlikely conspiracies are to go unreported, as even a small number of people being involved leads to the whole thing being revealed.
Note: Infowars can't even spell. I'm no spelling genius myself and make mistakes, but I don't publish articles. We all have spell checkers these days, so there is even less excuse for them. Its skepticism (or scepticism in the UK).
