actually if you look up the definition of the word status it is defined as

1. the relative, professional or other standing of some one or something....

to me that means a a persons or things...
gender,
profession/ career
what a persons rank with in their family, friends or any other place in their life,

the second definition of a persons status is defined as...
position of affairs at a particular time, especially in political or commercial contexts

to me that means a person can tell others
how they are feeling,
what they are doing
wishing others or one self well during the holidays
designate their political or commercial designations

in other words use the status line for telling others anything that they want others to know about their self and where they stand.

on social networking sites like facebook a status is a mixture of these tw definitions where people post to each other how they are doing , what they want others to know about their gender, sexual orientation, health issues, political views, things they are selling and other keeping in touch with family and friends.

I know you are looking for a place in your profile where you check off the word male or female but this site does not use that as far as I know, they dont need to because theres already a way provided where people can .....if they choose to.... designate whether they are male or female or other gender identifications....the status.

maybe a moderator can also check in about their or the sites views on this issue.
