Identity is a complex thing. It's an interplay of what a person declares about themselves and what society is prepared to accept as an identity. Who gets to decide identity is thus a mix of you and everyone else, and the weighting is dependent upon parts of your identity.

It's kind of a mess, and it's really not fair to anyone.

Anyway. Yes, anonymity carries its own baggage. But it's a separate sort of baggage, out there to be assumed by anyone at any time. There's a long and proud history of anonymous authors affecting politics or writing biting satire that would have been impossible without anonymity.
