I suppose some RL anti-puritanical groups do exist.
First and foremost...hippies. C'mon. Pony beads, VW mini-buses, mind altering drugs, promiscuous sex with many anonymous partners, getting stoned at the drop of a hat, playing guitars around campfires and protesting things that suck, like wars and big government and oppression and stuff.
The Roman Catholic Church - while not like the hippies, Catholics can drink, dance, and who do you think came up with Mardi Gras in the first place? The Puritans were a splinter group who thought that the mainline protestants, people who opposed the gold and wine and other percieved material offences of the Catholic church were themselves entirely too free and loose. Oh yeah, and you don't have to find Jesus either...they know where he is.
