The more I think about this question of obligatory gender identification for this site, the more it seems unnecessary to me for the many, very valid reasons already stated.
If I recall correctly, there was no indicator on our avatar or beside our name as to which preference we may or may not have indicated, on the original set-up of Stories Space. Nor was there a colour code.
I've been a member here since the first day the site went live in October 2010. What has mattered here are the writers, the readers, the stories written, the help given with writing stories, when it was requested, the friendliness and camaraderie of the members which developed both in the forum setting and privately.
As far as I can tell, the success or failure of a story is not based on the professed gender of the writer. The friendships made are forged on affinity, regardless of professed gender.
And this site, from the start and until now, has been a place for writers and readers. There are members here who have self-published their works or found an indie publisher. There are writers and readers here who are voracious readers, and who share their love of literature and the written word with one another. The exchanges based on all those things are wonderful, and they happen, as far as I can tell, between people who do not care a fig if they know how the other person identifies in terms of gender.
Nevertheless, it is well documented in the publishing world that many male readers shun books written by women. Based on that, the author of the Harry Potter books chose to be known as J.K. Rowling. So yes, knowing how a person identifies can be unfairly detrimental. Many of us know this from deep personal experience in our daily lives. To say the least, it gets very wearisome as the years go by
So you see, dear powers that be, there is far more to this question for many of us, than just a colour, a symbol, a drop down menu with a range of choices.
Speaking for myself, I do not think it is necessary for this site, nor that we should be boxed into a predetermined set of choices, unless they be something like:
Writer
Reader
Both
Other
Thank you for your work and patience.
