Hostile ground? That's easy.
Gender identity is listed, rather than simply gender, as in the previous incarnations of this website. I am interested by people's gender identity in equal measure to their horoscope sign, to whether their birthmark is on their left or right side, and to whether the mileage on their car is a prime number or not.
Yes, even back in the collarme.com days the banner across the top was "The Largest BDSM community on the Planet", and I understand that a community website is not precisely the same as a personals website.
However, knowing whether the person you're communicating with has an innie or an outtie is pretty important for me, and I suspect I'm not alone.
The other fields contain drop down options for some pretty concrete stuff. Height, Weight, Country, and age, for example.
Please consider that that I admire many things about the United States, and if I could have chosen my parents I would have chosen a nice couple in Kansas, but the truth is that I lay my head down in Canada most nights, and to mark my country as USA would be a lie. To mark it as Canada is the truth. Not my truth. If instead of which country I was located in, the principal option on this site was which country I most identify wth, then I could certainly truthfully mark down USA, and such a label would be rather south of useful to one who wants to know the very practical fact of where I am.
My age, height and weight, likewise may be measured against reality. With respect to age, you'll notice that people who identify as a little of the age of nine will write so within their profile, and not in the drop-down list, which thankfully only shows numbers of a legal age. One set of numbers is a lot more important to establish than the other.
So, JVoV, if the administrators of this site honestly believe that people would rather first search by gender identity than gender, or say, sex, then they may be under a misapprehension. Or perhaps I am. Maybe generally people really are more concerned with gender identity... in which case, as the Aussies say, fair enough.
But if neither the person who chose how to label that field, nor I, are confused as to what people actually prioritize in their searches, then I'm quite certain I'm on hostile ground.
Which is find, as that's where I do my best work.
