I doubt it. While it may limit your parent's capability (if he thought of it as a second language), I think it would a little presumptuous for him to imply it limits yours. I know lots of people who approach coding differently than I do, yet they still do just fine (even if I can't watch them code because it drives me crazy :).
It would be presumptuous if I was to say that not thinking that way would make you a bad programmer; I'm sure there are many ways to enlightenment. And many types of enlightenment, for that matter. But I would venture to say that being able to think of programming as language, is a strength. Whether you use this paradigm as the primary frame for writing software, is a different matter. I find it very powerful.
