I had a sort of similar story about my introduction to D&D, although it was still years later.
What you neglected to mention was that that hysteria over D&D took another decade and a half to cool down, particularly in religious circles. My introduction to the idea of Dungeons and Dragons actually happened when my parents told me that under no circumstances was I ever to play it. It was about 1990 at the time, and honestly, I had never really given D&D much thought. I was always told that it was a sinful game that makes people commit suicide - why would I want to play that?
Well, in grade 1 (1991), I met a guy who changed my young mind about D&D.. We had a similar situation to your story, where we were trying to make D&D characters and figure out how to play, but he figured he was oldhat about it - he played with his older brother and dad. So when I learned that D&D wasn't only NOT going to make me kill myself, but was actually a fun game that families could play together, I wrote my mom a detailed email (yeah, lol), about how ridiculous the negative hype over dungeons and dragons had been, and did as much research as a 7 year old kid with a computer could do, and gave her all sorts of evidence that showed that Dungeons and Dragons wasn't something to be afraid of.
It worked, and I have played D&D since, even inviting her to some of my later games to play. My dad was a bit more of a stick in the mud, and at one point threw out all of my Magic cards because he thought they'd turn me to the devil. He doesn't recall that, but I certainly do.
