Not so easy to agree to.
I would argue that your identity is everything about you, your Facebook data being part of your identity. Saying I have multiple identities is confusing. There is only one of me. Any slicing becomes challenging as there are no sharp lines between who I am on Facebook, Twitter, Google+ or LinkedIn. There is lots of overlap.
