I took this survey last night. They said it would take 30 to 90 minutes. It took me two and a half hours. I may have gotten more questions as I am nonbinary. In some circles it seems I am not "Trans enough" since I am nonbinary, but the survey had a lot of questions that fit.
The article rubs me the wrong way badly. They hold onto the outmoded idea that we are 0.5% of the population. There are a LOT more of us than that; it is the proliferation of bogus statistics like that which make politicians feel free to walk all over us... <Rant OFF>
