Not sure what relevance katydee's potential topics of conversation have on whether the username is a social norm violation (and it isn't a social norm violation standing on its own - although it does give the impression that the user is female).
The question I see being asked is " is my current username deceptive or otherwise misleading?" not "is my name a social norm violation?" The two are not fully equivalent questions.
When a person writes from personal experience on a topic closely related to sex/gender, a nome de plume that causes some readers to believe that the author is of the opposite sex/gender can (unintentionally) mislead readers by causing a misevaluation of the conditions that created the personal experiences discussed. On the other hand, if a person is writing ...
So, my current username often reads as female. This is not intentional, and I am not female. Some on IRC have pointed out that this username could be considered misleading or deceptive. I have no real attachment to it, but I do have a few articles that I've been discussing and planning on posting here, and I think it would be confusing for others if I changed usernames, making it difficult for people to follow the genesis of certain ideas. However, I also don't want to mislead anybody.
Therefore, I pose the question to the community: is my current username deceptive or otherwise misleading, and should I change it?
