High Inbreeding
Despite the fact that the Amish do not marry their cousins on purpose, there is a high risk of inbreeding in their families. Due to the small size of Amish families, they don’t have a lot of options when it comes to marrying another Amish person.
No Recruits
Another intriguing feature of the Amish is their aversion to evangelism. They have a long history of keeping non-members out and isolating themselves from modern life. As a result, it’s no surprise that the Amish refuse to recruit. Furthermore, the Amish’s most ardent supporters are unable to join the church.
