This is an interesting idea, but I wonder to what extent this view is only possible for people who aren't explicitly persecuted for their identity. How can you keep your "identity" small if it's written on your skin or on your marriage documents? Should these people simply disassociate from their identities?

I think as a general principle it's probably good to minimize your public-facing identity, however, the reductionism and broad generalization make this argument much weaker and misses the point about why people get so upset about identity.

In this age of social media I think this can't be stressed enough.
