"Am I Cisgender?"

Rebecca Reilly-Cooper does something really clever here that enables her to essentially argue that the concept of a transgender identity is incoherent--in other words, articulate the "terf" position with a priori arguments alone, and so without relying on any contestable value or faith claims, or personal animus--while talking only about and for herself and thus without writing about and criticizing other people and their beliefs.  She does this by beginning her path to an analysis of the trans concept with an analysis of how she identifies and whether, not believing herself to be trans, she should identify herself as cis.

Of course, this doesn't prevent her from being attacked as anti-trans and a positive threat to trans people anyway.
