"...the limits of liberal secularism (think of violence against Catholics after the French Revolution)..."
Although the Ecclesiastical Hierarchy and the Nonjuring Clergy were always mainstays of reaction, "violence against Catholics" was insignificant until the White Terror of the Vend´eean uprising. When it came, the violence, despite sometimes terrible excesses (one of which is immortalized in Poulenc's opera) was legitimate revolutionary self defense.
