Skepticism, Science & Pseudoscience

I prefer on the whole to use 'pseudoscience' or 'quackery' or 'anti-science' or 'religious fundamentalism', etc., just for the same sort of reasons that you do: 'woo' is somewhat imprecise and over-inclusive and doesn't make it clear what the argument is.

HOWEVER, I will still use 'woo' or similarly inclusive terms for the type of theory or site, which is explicitly dedicated to opposition to just about everything that could be seen as 'mainstream'; and to treating it as some form of conspiracy. Such sites tend to combine right-libertarian hatred of government; distrust of 'western' medicine in general and vaccines in particular; 9-11 'truth'; distrust of 'conventional' science; belief in the occult; and often racist or anti-Semitic conspiracy theories. Examples of such sites are whale.to and Cassiopeia. For such sites, and people with similar viewpoints, it is not that they have a particular belief in, for example, MIHOP or that vaccines are dangerous, but that they explicitly reject all scientific or empirically-based viewpoints as suspect.
