Liberal Democrats don't get their heads chopped off for opposing the power of the state. They subvert the power of the state and use it to terrorize their enemies. If you're looking for someone in More's day who resembled a liberal Democrat, you ought to start with the Bill Clinton of the 16th Century, King Henry VIII -- the very man who signed More's death warrant.
While at Lincoln's Inn, he determined to become a monk and subjected himself to the discipline of the Carthusians, living at a nearby monastery and taking part of the monastic life. The prayer, fasting, and penance habits stayed with him for the rest of his life.
You know any liberal democrats who wear hair shirts to express their sorrow for their sins, and who get up for prayers every day at 3 a.m.? Nope, neither do I.
