An interesting diversion....
I'm sure you will all have read of the Nashville school shooting. There are a few interesting things about it. Firstly, shooters are almost always men. I think there are only 3 or 4 shooters on records going back to the 1970s who were women.
Secondly, despite all the news articles reporting that the shooter was a girl / woman, the shooter was in fact a man. In all articles where a transwoman commits a crime, they are referred to throughout that article as "She". It's notable that although the shooter was a transman, all of the articles refer to him as "she". Surely this should be being called out? This was a man doing the shooting not a woman (if we are to keep to established standards).
The more concerning aspect is that there have been 2 or 3 shootings now in the last couple of years where the shooter was an FTM / transman suggesting (given the statistical background of almost no women shooters) that perhaps hormone treatment could be a factor in the shooting. To my mind, this is another reason for investigating the issues with prescribing hormone treatment.
As it happens I've posted something on the 199 thread that addresses many of your points. The attacker was a female born person who had a diagnosis of high functioning autism and who had been recently been receiving counselling. Recently they had started to identify as a man, so we might safely assume that they were a trans man in the very earliest stages of transition.
There was some new identity on the net including a profile on Linkedin, but what was left as a suicide note left to a best friend was signed Audrey. There's cause to doubt that testosterone was an influence.
If testosterone was an influence as some seem to claim, and also claiming that testosterone influences brain activity, then those saying it need to stop saying the opposite in the case of trans women where they will tend to say that female hormones feminise the body but not the brain.
We can expect some punching down from the right wing press on people with autism, those with some mental health need, those people who are seen by others as 'loners', those people who are struggling with identity etc. People will deny that guns are the issue, but that the wrong kind of people are. There is no single issue.
