I am not entirely against “thick” libertarianism, though in the past I may have expressed some skepticism about the popularity of the issue in libertarian circles. I can think of at least one attitude not strictly entailed by liberty that is almost certainly necessary for liberty to be maintained in a culture.
It is not anti-racism, or anti-sexism, or any the usual shibboleths of leftism. And it is not patriotism, a commitment to objective value, or a belief in a deity, as so often preached on the right.
It is the predominance of “mind your business.” That is, it is not being a busybody, and paying responsible care for the things one can most control, that is of paramount importance.
