I had a bit of a revelation this morning about the difference between transsexual people and transgender people.
Transsexual people want to be their chosen sex, but know that they aren't and they also know that is a mental illness. That means they don't force acceptance. From what I can observe, it is generally traumatised, same-sex-attracted people and therefore it also makes sense for them to be part of the LGBT because they are same sex attracted. They also consistently push back on any type of transitioning for kids, either social or medical/surgical.
Transgender people think that they ARE their chosen sex and acceptance is either mandatory or harmful to THEM. This is displayed by the constant victim narrative. From what I can see, it is a mixture of SS-attracted and OS attracted people- and they are either adolescents or have a personality disorder as adults.
This is why it is too complicated to put them under the same umbrella. Both groups have a mental health disorder that is severe and persistent body dysmorphia, but TG also have a personality disorder, or an unstable sense of self. This is the reason why psychological assessment (not affirmation) needs to be at the heart of transitioning.
People like Dr Upton do not have the emotional capacity to see that they are men and deal with the dysphoria, and therefore choose aggression when they are reminded that no one else (not even their partner) sees them as such. They are dangerous to women BECAUSE they are Transgender and therefore have been given access to spaces and vulnerable women and have been proven by the Sandie Peggie case to not respect their boundaries.
