I relate to the third paragraph. Being born and raised in that organization, it took some time for me to learn about real relationships, real connections with people, etc. Very interesting thoughts.
When people are removed of their own capacity of thinking and making decisions for themselves, it shouldn't be surprising that they will not be capable of having real relationships with their loved ones or show love properly, even if they truly love.
They are told that their own feelings for their loved ones are secondary, that their stupid Jehovah (and somehow they get convinced that anything and everything that the WT says is their Jehovah's word) supersedes everything and everyone. They are to let loved ones die before taking proper care of their health as per their own Jehovah nonsense. Of course, they would be unable to express or act upon the love they feel for others.
It's not that they don't love; it's not that they don't have the capacity to love; it's that they can't love because of their brainwashing.
