Nice people unless you want to leave. They split up families.
My Mother-in-Law is a JW as was my Father -in-Law before he passed away.
My wife had to leave the family home because she refused to become a JW and she didn't have a relationship with her parents for quite some time afterwards. Eventually, they sort of reconciled, but it was never easy because of the religion and it still isn't.. Wife's younger sister was recruited to the JW's at a young age, but she rebelled, which took a lot of courage. Again, she had to leave home at a very young age and went to live with my wife in her rented house.
Trauma all round and certainly the splitting of the family was a direct consequence of the JW's.
I could go on with other tales, but you get my drift!
