Yeah, it's not for research study, just an attempt to get a better idea of our community. I put 'Assigned sex at birth', because I didn't want the gender people identify as to play a part, since like you said, there is a genetic component to stuttering that is far more scientifically relevant. If a trans stutterer took this and chose the gender they identify as, it would have been an inaccurate view of how their biological sex played a part in their stutter. So this was my way of asking 'XX or XY', but not everyone knows what that means, and most people don't actually know their karyotype. Some people are even XYY. This was the least confusing way of asking for someone's initial biological sex. For reference, there is another question farther along in the quiz that asks people how badly they stutter around people of the same gender, and then around people of another gender (outside of attraction, of course, which another question). The social construct of gender is (imo) also important to take into account at times, because how we react to gender might play some in part in our comfort or tension around them. [And I think the results show there is a little merit to that theory](http://i.imgur.com/9N5Zyky.jpg). So I tried to address that aspect as well. But if someone doesn't want to participate in the survey because they are offended by the way a question is worded, then that's totally fine. I passed it by many people, two of them trans people, and we all agreed this was the least confusing way of obtaining the data we wanted. I feel good about it.
