Earlier quoted context omitted.
Seems like a pretty crazy claim, want to share your reasoning?
Merriam-Webster: "Ideology: a manner or the content of thinking characteristic of an individual, group, or culture" No ideology = no characteristic thinking. If you think you don't have ideology, you probably have the dominant one. Or don't think.
Just because A -> B, and we have B, doesn't mean we can conclude A.
Sure,
Idealogy -> a manner of thinking characteristic of an individual, group, or culture
But A manner of thinking characteristic of an individual -> idealogy
Doesn't follow from that!
