There's a community in New York state (a place called New Square, one hour north of Times Square) which segregates men from women, the women aren't allowed to drive or walk on the same side of the street as the men. This is a highly religious community, but one where recently there has been some serious outbreaks of violence within the community - with one member almost dying in an arson attack!
Fascinating insight into a religious community in the USA in the 21st century:
