I'm sorry to anyone who knew the victims, and their friends and families.
I was more struck by the various mental health diagnoses than the focus on sexuality.
I used to be friends with someone with EUPD and depression, and a self diagnosis of PTSD. He's also been convicted of spitting at police officers in the past when resisting arrest.
We fell out when I disagreed that his last-ditch plans were reasonable; he felt that because he wasn't getting the mental health support he needed, he would be justified in going and stabbing someone random.
Apparently the idea was that he'd probably get appropriate help in prison; also he decided that everyone would be horrified by the lack of mental health support available to people with his diagnoses, which would lead to the entire mental health system would be reformed.
Sorry if I haven't explained that very well - it just triggered the (really disturbing) memory.
