Ron is clearly meant to embody the everyman archetype. I think that's all people mean when they use the word "normal." It doesn't mean you have to relate to him or that you're abnormal if you don't. Just that a lot of people probably would relate to him as a character who has some good traits and some bad traits but overall isn't very remarkable.

He isn't a victim, so if that's your standard for relatability (as it appears to be in the wording of this secret), then no, Ron Weasley probably won't work for you.
