2. [Liberalism] consists of a set of commitments in political theory and political philosophy, with concrete implications for politics and law. In North America, South America, Europe and elsewhere, those who consider themselves to be conservatives may or may not embrace liberal commitments. Those who consider themselves to be leftists may or may not qualify as liberals. You can be, at once, a liberal, as understood here, and a conservative; you can be a leftist and illiberal. There are illiberal conservatives and illiberal leftists. Historically, both Republicans and Democrats have been part of the liberal tradition. Right now, some Republicans are illiberal, and the same is true of some Democrats. [...]
20. Liberals think that on both left and right, many antiliberals and postliberals have manufactured an opponent and called it liberalism without sufficiently engaging with the liberal tradition or actual liberal thinkers. They think that some antiliberals wrongly conflate liberalism with enthusiasm for greed, for the pursuit of self-interest and for rejection of norms of self-restraint. They think that some antiliberals describe liberalism in a way that no liberal could endorse. Liberals agree with the Nobel economics laureate Daniel Kahneman and his collaborator Amos Tversky, who complained of those who try to refute a position by mischaracterizing it: “The refutation of a caricature can be no more than a caricature of refutation.”
