CMV I believe there are only two genders. And you can only claim to be one at a time.

Now, first off, I would like to say that I believe in transgender and transsexual people. I think people can have a different gender than their birth gender. However, in my mind, there are only four options as far as the whole of gender options: male, female, mtf trans, and ftm trans. 

And, at any one point in time, each person is either male or female (or transitioning, but I don't consider that a separate gender).

Also, I believe that the bathroom you use is what YOU think you look like. So, no matter how much you feel like you're a woman, if you have a beard, use the men's room. If you are sporting double ds, you should go to the women's room.(These are extreme examples)

Feel free to CMV on anything I mentioned.

Well first, lets examine the likelihood of this, biologically.  Do things in nature tend to come in binaries or spectrums?  Within the characteristics of a species, it's easy to see it's the latter.   People are not "5' or 6' tall", they run an entire range of heights.  Similarly with hair colors (even blonde varies) or shades of skin color, or other characteristics, such as eyesight, foot size, hearing acuity, etc.

Secondary and Primary sex characteristics come on a similar spectrum.  There are many people who possess both or none of the traits associated.  

Now, question: why would this spectrum all of a sudden snap to binary?
