I'm sorry you got offended, though I understand my wording may have proved to be a bit harsh.
I'm very well aware of the aforementioned distinction between the definition of Sex and Gender, yet I firmly believe that Nature points out our roles rather clearly with the genitalias gifted to us - but this is probably no place for any hint of rejection considering your personal situation that you shared in another topic; so again, I apologize.
But, what you failed to notice in my previous (and admittedly negative) comment by your sudden "rage" is the warning/heed of advice which others already mentioned before me, and the reason why you actually shouldn't get offended: A 'label' like this is an outstanding invitation for malicious people and further offenses or simple ill will - a phenomenon that can be hardly avoided over the internet, either made openly or not -, no matter how many and how strict rules are regulating the Forums, especially considering how sensitive you are (or others may be) in the matter.
Apart from that (like it was also mentioned): this is a gaming community. Even if you're among "friends", others befriend/respect you mostly because of your personality and/or your experience with the game; just be cautious about what you're sharing about yourself with others and be prepared for rejection and/or opinions that could be conflicting with yours.
That said, I'm fine with the addition of 'Other', though I still see it unnecessary.
