I get the feeling your definition of "ideology" is a very specific, politically-motivated one, and not the one that most philosophers and social scientists have concurred is an appropriate default definition over the last 50-70 years. Everyone carries ideology with them. It is the source of subjective interpretations and judgments. And unfortunately for your position, we have more or less come to the consensus that all language and communication is fundamentally subjective: this means that no statements or actions are without ideology.
