And I really wish postmodernists would stop hiding behind the banner of "the humanities". Analytic philosophy, history, classics, religious studies, and art history are all capable of making meaningful and even true statements from time to time, and most of them can be made comprehensible to the typical person.
As for the humanities thing, yes, I agree. Just as physicists can make many clear statements that resonate with people who don't even know math, there are many aspects of the humanities that are accessible and clear to people who have never studied theory. Your disdain for higher level theory would also make it difficult for you to enjoy certain texts by people like Aristotle, Kant, and Hegel, none of whom are "postmodernists".
I agree that there are lots of things that are worth understanding but can't be expressed in rigorously logical terms. Things like the subjective experience of falling in love or laughing at a joke or the value of behaving toward others with compassion. Wovon man nicht sprechen kann, darüber muss man schweigen.
