I don't really understand the problem. First, I think it's risky to even begin to evaluate whether the people you interact with are more or less intelligent than you. Intelligence is context-dependent. Most of the people you think of as less intelligent probably have a context where they're smarter than you.

"Don't compare yourself to others, for it will make you both vain and bitter; there will always be someone worse, and always be someone better."

Second, what does it matter? When people say things to me that I consider dumb (that can happen both from people less intelligent than me and more intelligent than me), it's rare that I actually need to correct them. Get a sense of when it matters and when it doesn't, and if it doesn't then just let it go.
