Tell it to those slaughtered in the Peasant's Revolt or by Cromwell's minions.
And that has more face value to you?

Respectfully, Jude -- Calvinists are hardly liable either for Martin Luther's over-estimation of Princely Authority (which resulted in the massacre of the Peasants), or for the excesses of Cromwell (who was the anti-presbyterian Warlord of the Independency; a "Calvinist" of sorts in his Soteriology, but not in his Ecclesiology or Theonomy).
"Calvinism", if read in the light of Calvin's Institutes, rejects both the Tyranny-prone Monarchism of Luther, and also the Demagoguery-prone popular-Congregationalism of Cromwell.
Calvin established that, amongst both Presbyters and Magistrates, the Presbyterian-Conciliar or "Republican" form of Government -- with its delegation of powers and checks-and-balances -- was the pre-eminent Biblically-ordained form of Human Government.
We Presbyterian Calvinists can hardly be held to account for Luther's crimes; while Lutherans burnt Calvinists at the stake at Leipzig, we Calvinists have always regarded the Lutherans in love as our elder brothers in the Reformation of the Church, if only reserving that they should recognize that Calvin perfected what Luther began.
Nor are we responsible for the excesses Cromwell; according to both the Bible and Calvin's Institutes, the proper form of Human Governance is Presbyterian-Conciliar or "Republican" governance, not the Populist-Demagoguery of Cromwell's Independency.
