Pat, you would fit exactly as you say. It has nothing to do with bits and has nothing to do with gender expression. It has everything to do with gender identity. You expressly state you have an identity that is not man or woman. My point is that if someone has a variation in gender expression, it has no bearing on their gender identity. Being non-binary or transsexual are variations of gender identity. Crossdressing, by itself, is gender expression.
I work with transgender people of all types and crossdressers. Have many friends of all types. I support all. What I do like to do is educate on what the difference really is. Otherwise, it is a detriment to progress as it becomes confusing for the layperson. Heck, it is obviously confusing for the non-layperson, just look at this thread.
