Your dad called you. I found this interesting. He either was interested in the opposing views that you held or he was calling with helping you in view.
My dear mom was a true believer but every once in a while she would express being disturbed by a Watchtower point of view or elder’s opinion. To me, I figured she might be ripe for hearing negative things about The Truth. We would talk many many times and I would put her in a corner and she just couldn’t handle it. Eventually I seldom mentioned these things. Why?? Because I realized I couldn’t out argument her. She would know throw 50 years of believing what she felt was truth down the toilet. Rather than pursue the religion I realized she was old and I would rather cherish her for being my mother.
In the end, it’s all up to the person. For some, logic isn’t the issue.
