Male pattern violence is more ingrained in male people as a class.
Have you any evidence that isn’t specifically related to testosterone?
There is evidence that (transsexual) trans women who transitioned after 1989 are no more likely to commit violent crime than non trans women, and females to males who take testosterone are more likely to commit violent crime than females.
No.
Here's a comment I posted earlier on Djeine at al:
This study showed unequivocally that the cohort of male transsexuals analysed were at the exact same risk of being convicted of a crime as the male control group.
While it did show for the early cohort that male transsexuals were more likely to be convicted than the male control group, that was not true for the later cohort.
The study explicitly notes that male transsexuals were compared to controls from their birth sex. No confusion.
Male rate of crime compared to male rate of crime. The control groups were always compared to the cohort of the same sex.
For the avoidance of doubt that means male transsexuals were compared to male controls and female to female.
And no, the study did not find that during the early period female transsexuals committed crime at the same rate as the male control group. It found that compared to female controls, their risk was 700% higher of being convicted of a violent crime but 40% lower compared to male controls. For all crimes the figures were 400% higher and 30% lower respectively.
As for the second period, here is what we do know:
The study compared risk on the basis of sex. The second time period shows the risk for both sexes together to be just slightly lower overall (10% less likely to be convicted than control groups of both sexes).
Because the male risk of being convicted is so much higher than the female one, the one thing we can say with confidence, is that the study conclusively showed that not even male post-op transsexuals reached female rates of criminality.
And at no point in the study is there even the slightest suggestion that as you claim "trans women's decreased to the level of the women's control group". They did not.
Very helpfully, if you dig into the accompanying information (not mentioned directly in the study) you'll find two tables provided as Word documents where the authors compare outcomes for the transsexual cohorts first to their "final" sex and then to their birth sex.
This shows that compared to female controls, male transsexuals over the entire period are six and a half times more likely to be convicted of any crime and 18 times more likely to be convicted of violent crime.
Unfortunately, although the authors calculated the risk for each time period separately, they do not provide the numbers for the latter period by sex.
However, very helpfully Dhejne herself clarified the issue in an AMA on Reddit in 2017. You can read her full comment here.
In this comment she confirms that male transsexuals exhibited a male pattern of criminality for the entire period.
She says:
If one is only intrested in transwomen data is only available for the whole period. For only assigned med who had transition 1973-2003 they had committed more crimes than cis women and more violent crime than cis women. [...] Having a male pattern means that they did not differ regarding any crime or violent crime if compared with cis men.
In the interest of a respectful debate in good faith, may I suggest therefore that it would be helpful if you could read the study again, familiarise yourself with the actual findings and clear up your confusion so that you do not risk spreading misinformation as you have in this thread.
