This is a new account for privacy by segregation of interests, but I am not a new user.
WP:SOCK#LEGIT states that, "A person editing an article which is highly controversial within his/her family, social or professional circle, and whose Wikipedia identity is known within that circle, or traceable to their real-world identity, may wish to use an alternative account to avoid real-world consequences from their editing or other Wikipedia actions in that area."
Among other such reasons, my primary Wikipedia identity is traceable to my real-world identity.
