Another thing to consider: dax never talks about actual trans topics like gender politics and the change of perception in how people treat you, emotional shifts, change in sexuality/loss of erections, tits that hurt, or learning to groom from level one. It is only ever about vapid, superficial shit. This makes me think Dax - if they're trans - has not taken a single estrogen pill.
Keep this in mind when you read her posts. But don't take it as gospel either. I could totally be wrong, just an observation.
