I have to wonder why any document would even ask such a thing. After all, what difference does it make if:
You use a men's or ladies washroom as long as no one is offended. (I have been in crowded pubs and seen women invade the men's washrooms just because of the lineups.)
You can perform a job as required. (Who is to determine that sex has anything to do with it?) We have male sales clerks and female firefighters. BFD.
Your credit card is used to buy lingerie or fishing gear. (I know this could be construed as sexist but I am only using it to make a point.)
Your voting registry is going to be affected by your sex/gender.
I think this list could go on and on, but the point is made. The only one outside of your partner and yourself who needs to be concerned is your doctor. S/he is the only one who has the right to ask that question in my opinion. Any other use of this question can be considered as discrimination or have the capacity for discrimination.
Just a little :mad:
