That's not what GP means by "liberal"; "liberal" in this sense refers to the belief and support of the current "democratic" establishment, the right to private property, the idea of human rights, and freedoms defined as matters of separation between people (i.e. the assumption of the person or people attempting to take them away rather than a positive conception in human community). In this view, both US 'liberals' and US 'conservatives' are both liberal. Thus, what GP means by 'non-liberal' includes the critics of liberalism, most notably ones on the left.
