A lot of forms ask you for your gender. Firstly, many of them really don’t need to know. Secondly, they often only ask if you are male or female — which is fine if you are, but if you’re not means you have to lie, pick something incorrect, or not answer. That can only hurt everyone, from the trans* person involved to the statistics which are going to be wrong.
Therefore, we’d like to see gender boxes removed from all forms which don’t need them, and for any form which does actually require gender to allow you to write it in. That way, anyone who is not male or female can explicitly identify themselves and be recognised as such.
