What it means to be transgender

It’s a physiological birth defect. My brain and my body received inconsistent blueprints, which left the brain in chronic distress over the mismatch. A mental illness would suggest there was a “healthy state” prior to being “ill”.

I came accross this quote today which was in response to an assertion that transgender equals mental illness. The writer gives a clear explanation which hopefully makes sense to those who find it difficult to understand.
