When I was a somewhat devout JW (people often say Jehovah Witness as a noun, but that always bugged me grammatically since properly stated it should be "Witness of Jehovah), I told a nonJW Christian friend that I couldn’t be “unevenly yoked with unbelievers.” She (who wasn’t interested in me, she was trying to matchmake me with a mutual friend) got offended since we should all have been Christians and she felt I was calling her an unbeliever.
Certain denominations have so very different beliefs that if followed to their logical conclusions they shouldn’t be able to have relationships, but so many people bend the rules. I fortunately am no longer captive to that ideology, though I do think I’m permanently damaged. Still, not as damaged as people who went through sexual abuse. My stuff is mostly mental and will probably just mean I’ll never have a romantic relationship.
