But more frustrating than pure semantics is that liberalism’s most ardent defenders tend to credit the liberal order for victories won beyond the means of properly liberal politics. More often than not, the march toward justice in liberal societies has been fueled by illegal strikes, civil disobedience, riots, and, at times, the threat of violence — not merely winning arguments in the “public square.” If we always played by liberalism’s rules, abiding by its preference for legal and parliamentary procedure over open revolt, the progressive victories now attributed to liberalism’s natural egalitarian tendencies would never have been achieved.
