Final answer:
While labels such as "isms" are common in society, nonbelievers, "nones," and proponents of existentialism and post-modernism illustrate the potential for individuals to reject these labels. Despite societal pressures, some people assert their autonomy over identity and resist definition by external categorizations. Yet, completely avoiding all "isms" is challenging due to their prevalence in societal structures.
Step-by-step explanation:
It is debatable whether a person can exist without being labeled by any "isms," as societies often use such labels to categorize people based on their beliefs, characteristics, or identities. Nonbelievers such as atheists or agnostics, do not align with religious labels, but this does not mean they lack moral frameworks. Moreover, the rise of "nones," individuals without religious affiliation, shows a trend of people distancing themselves from traditional labels. Furthermore, existentialism and post-modernism suggest that individuals have autonomy over their identity, irrespective of societal labels.
Existentialists assert our capability to determine our own essence, while post-modernism questions the concept of an objective reality. Ultimately, though societal pressures and labels exist, individuals can embrace a multiplicity of identities and resist being defined solely by external categorizations. However, it is challenging to completely avoid all "isms" due to the entrenched nature of classification in societal structures.
