In earlier times, identity was mostly a function of social relationships. This seemed to be a lot more concrete than abstract concept of identity that is popular in industrial societies. Here are some other things that might inform/create identity besides political opinions shared on twitter: race, religion, ethnicity, nationality, gender, occupation, consumption preferences, skills, activities, appearance. All of these are ideas to some degree, but some are more concrete than others. But ultimately, identity itself is an idea and I don't think it can be fully separated from other constructs of the mind.
