In common usage, ignorant means "ignorant." Only people ignorant of the meaning of ignorant understand ignorant to mean "stupid."
If you are reading an educated man's writing where he correctly uses the term ignorant and interpreting it to mean "stupid," then you're either an idiot yourself or you're deliberately misinterpreting the statement.
