Home grown, organic breasts? Sign me up..
Just kidding, seriously, sooner or later Amish girls return to their close minded world views, unless you seriously see yourself converting to their lifestyle and religion, I suggest you avoid it completely
There are lots of mennonites in TN, not the same thing, but close enough. There are 7 billion people in the world, more than half are women, surely you must be able to find a non Amish girl you like
However, if for some reason you are in love with one, and there is truly a deep, genuine connection, who am I to stop you? If your intentions are pure, there is a chance the family would be rational enough to accept her departure, after all, they DO give them the choice.
I will add though, they let them explore the real world, trusting they'll quickly return to the Amish life style.
However, if you want an "Amish girl", without the Amish part, just date a Christian girl who doesn't go to church anymore. She'll have the relatively same, home grown, pure girl next door type, just very open minded and very fun to be with. Mind you, she will always be thoughtful, kind, warm hearted, and a little more moral than most girls but that won't stop her from being a total slut.
Personally, I think God is going to slap them upside the head several times for lacking common sense and not accepting technology, science, and all the wonders of his modern world. God likes video games, that's why he gave us thumbs...= )
