Why do existing states often view different forms of community identity as potential rivals?

Because community identities may create alternative sources of loyalty and belonging that compete with the state's attempt to build a unified national identity.

The correct answer is Option 2: Because community identities may create alternative sources of loyalty and belonging that compete with the state's attempt to build a unified national identity.

Option 1: Because community identities can become the basis for political demands that challenge the existing national identity promoted by the state — Correct but less precise. Community identities may sometimes become the basis for nation formation and political claims. However, the main concern of states is that these identities can compete with the single national identity they seek to promote.

Option 2: Because community identities may create alternative sources of loyalty and belonging that compete with the state's attempt to build a unified national identity — Correct. Existing states often view different community identities as rivals because language, religion, ethnicity or other forms of identity can create loyalties that differ from the state’s preferred national identity.

Option 3: Because community identities based on language, religion or ethnicity often encourage communities to seek complete separation from the state — Incorrect. Community identities do not necessarily lead to demands for separation. They may simply seek recognition, representation or preservation of their identity.

Option 4: Because states generally consider cultural differences as obstacles to creating a stable political system — Incorrect. States may view diversity as challenging, but the issue is not diversity itself; it is the possibility that identities may compete with the dominant national identity.

NCERT: There is no necessary relationship between any specific form of community and the modern form of the state. Any of the many bases of community identity (like language, religion, ethnicity and so on) may or may not lead to nation formation – there are no guarantees. But because community identities can act as the basis for nation-formation, already existing states see all forms of community identity as dangerous rivals. That is why states generally tend to favour a single, homogenous national identity, in the hope of being able to control and manage it. However, suppressing cultural diversity can be very costly in terms of the alienation of the minority or subordinated communities whose culture is treated as ‘non national’. Moreover, the very act of suppression can provoke the opposite effect of intensifying community identity. So encouraging, or at least allowing, cultural diversity is good policy from both the practical and the principled point of view.
