Briefly explain the three reasons why primordialism fails to answer why identity becomes politicized

What will be an ideal response?

The three key reasons are as follows:
First, primordialism cannot explain the emergence of collective identity. To the extent that any form of identity emerged only relatively recently, it cannot explain what caused that form of identity to emerge in the first place.
Second, primordialism also cannot account for change in the meaning of different forms of identity, no matter how old. The political significance of ethnicity, religious affiliation, gender, or other forms of identity are not timeless, regardless of whether people believe they are.
Finally, primordialism also ignores the possibility that individuals can and do choose—and sometimes change—their own identities. While it is true that individuals develop powerful emotional and psychological attachments to identity groups early in life, they may also adopt new and different forms of identity later on.
