Culture in the Blender

My psychology of culture textbook tells me if you consider a culture to include all individual variations within the culture, cultural differences disappear. For example, the differences between Japanese and American culture disappear. Maybe that’s why it’s so easy as a TCK to take a part of a culture that you like and use that and still find some people that agree, even if most don’t. I wonder if that also means that for any individual TCK, trying to classify your ideas culturally is a waste of time. If internal cultural variation can be so large that you can’t tell cultures apart if you don’t worry about how many people think a certain way, then how can you really claim that an individual is or isn’t part of a culture based on that they don’t think the way the majority thinks?
