People who cut themselves off from the jewish community
Not only do they not keep shabbos, kosher etc, They marry non-jews and move to places where there arent any jews or very few of them.
Many people who ive met that are “OTD” want some connection to judaism so there is hope for them, but then there are others who seem to totally cut themselves off , its much harder to do teshuva when you move outside NY (especially down south) marry a non-jew and have kids
