John Voorhees and Michelle Rossi-Voorhees

I agree with what you about what are saying about those escaping religious persecution, wanting a new opportunity, or eventually forcing their own religious beliefs on to others. However, I think the Voorhees were a stretch to fit into that because they were not people with beliefs adhering to 17th century laws. They were 21st century people bucking and rebeling about a project on the 17th century. Thus, we really did not get an accurate portrayal of how they would have handled things or would have been expected to perform in the community. I can see people refusing to go to church and rebeling against society and the law in the 21st century. I don't need to go back in time and do it with costumes on. What would have been better would have been seeing them have their beliefs in private and letting the viewer see how they handled it with each other and how they were able to deal with this on a daily basis. How well did they hide it? How much could they be themselves without being found out or punished?
Saying this, it would have also been fine to have had them be vocal and still follow 17th century codes of conduct. Acting out regularly against what the norms of the time would have been on a regular basis violated the reason for being there. How is this different than refusing to be a servant or refusing to work in the garden or insisting on taking turns on sleeping in the bed with the high freemen? You can't change the codes of conduct or it compromises the experience and the expereince of others. They just got away with what they rebeled on because it was religion. Their actions also allowed the others to become somewhat laid back in following the laws as well. It created a bad situation and opened a Pandora's Box. They should have been booted. I think Governor Wyers showed great restraint and atrempted to compromise. Had he not, I think there would have been a blow-up or the prject would have fallen apart all together. I think he knew this. Why ruin it for everyone who really wanted to be there and have the experience?

Whether or not the Voorhees agred to such a thing, we don't know. However, an online interview with the Wyers family SUPPOSEDLY stated there was. Being stong in your convictions has nothing to do with how you participate. I am sure the servants did loads of what they didn't want to do.
I am still not convinced that the Voorhees acted according to plan. The Heinz couple was liberal and far left and I don't think they acted fully as to how they would have liked in many situations.

-"extremely annoying to listen to those religious people sing religious songs, and I was annoyed when they read pasages from the Bible"-

This is COLONIAL HOUSE. It was appropriate for the setting. Religion was a major part of the lives of the era. It was not out of place. Had it been Imperial Japan House, Sioux House, or ancient Egypt House, I could see your point.
Their actions are about as ridiculous as a conservative Bible believing Christian volunteering for India House and balking because they have to pretend to be Hindu. Before volunteering, a conservative Christian knows that Hinduism will most likely come up and that you might have to attend a Hindu temple and discuss Hindu prayers and rituals. If you don't, I have a lake I want to sell you on the moon. (If the producers expected the couple in question to do this to this extreme, they obviously wanted ratings from sensationalism and not an educational and beneficial project on our connections and reactions to the past.)
If a conservative Christian went to India House, they should realize that they are there to experience on TV what it would be like for a 21st century person to live the lifestyle. You are not being asked to be converted. You are being asked to participate in an experment to compare how a 21st century person might react in an historical environment and get a window into how a previous century person might have had to deal and live in life.
It is fine and expected that you might discuss your dislikes and frustrations. However, to refuse to particpate and attempting to violate the lifestyle of what you hope to imitate is down right ridiculous.

-" They were there to thrive as a community, not praise God/Jesus."-
To a colonist in the 17th century, this was part of thriving as a community. It fit the era and the project. It is true that not all people of the era came to the continent for religious reasons. I have a B. A. in history and have known this for ages. However, religion permeated all aspects of life-religious or not. I live in 21st century America and don't believe that medical care should be a part of capitalism like buying a car or house. Guess what? Too bad! I live in the 21st century and have to do it anyway!
