From the article:
Veer rightward instead, and you’ll be similarly disappointed. There, truth isn’t much different, although they wouldn’t call it “situated” (but it is). It is the kind of capital-T “Truth” that’s both “obvious” to everyone and too simplistic to be true,
Funny, but this whole article is just as "truthy" as what it complains about.
When it comes to basic cultural eras, which is what is being argued here, you have to make a choice. For instance, with respect to religion and government, should the government outlaw religion, as the postmodernist left wants, should religion be supreme as most of the premodernists want, or should we have the tolerance of modernity.
And which choice you make on this issue is deeply tied with similar other issues like science, technology, economics, education, sex roles, and so on, in three whole bundles. If you think you can pick and choose and come up with a society that doesn't fall apart quite quickly, you are quite mistaken.
