I don't feel like gender is relevant. Plus, unless there is an "Other" option it might make those of us (like myself) who are trans or identify as gender neutral feel ostracized. Of course, they could pick the gender that "best describes" but take it from me, that can cause more problems than it's worth sometimes.

I don't care if people assume I'm male. I don't care if they assume I'm female. Either way, I'm still human.
