Well it's typical woo argumentation for starters, claim that your assertions are backed by science and then spend page after page refusing to provide scientific sources, but instead throw out whatever you can find that isn't an actual scientific source (from government bodies to opinion pieces in pop-sci magazines etc).
One of the central tenets of postmodern ideology is also that scientific findings must be subservient to what postmodernists believe to be a progressive political agenda, see Sokal's and Bricmont's writings on the subject for a good exposition. One can see this reflected in LondonJohn's grandiose claims of his own purportedly progressiveness and the denunciations of his critics as reactionaries - such denunciations in lieu of arguments also being a cornerstone of postmodern argumentation.
It mostly just shows how pomos, not having the slightest clue how science works (or indeed how logic or even basic reasoning skills work, in the case of LondonJohn), believe science should be. When asked for a scientific source to back up their assertions, they don't hear "Please provided a peer-reviewed paper in a high-impact journal containing the evidence for this assertion" but they just hear "Please show me an Authority who asserts this." As far as they see it, science is (or rather should be) nothing more than Authorities making bare assertions. Well, "progressive" Authorities at least, not the "reactionary" ones.
Again, Sokal, Bricmont, and several others have written extensively about this. It was cute the first time around but now it's just annoying. Something about history repeating first as a tragedy and then as a farce, I suppose.
