Can anyone point me to any stats on whether fully transitioned males (mtf) are any less violent than men as a group generally?

Dogs that are aggressive are sometimes castrated in an attempt to modify their behaviour, however it’s wise to use temporary chemical castration before moving onto surgery. This is because the results of reducing testosterone are unreliable and can, counterintuitively, increase aggressive behaviours. It’s believe this is because testosterone can act as a kind of confidence booster, so that dogs who are fearful can be made more fearful.

Obviously the results in humans might be different, however in dogs, it is absolutely not a straight line between decreasing testosterone and decreasing aggression.

I think it might have been Ken Zucker who also noted that many men who transitioned developed a kind of jealous rage against women as they realised that however hard they tried and whatever they did, they were never going to achieve womanhood, which women (of course) had handed to them effortlessly.

Agreed, but Leafstamp's point is a good one - it's not just about safety.

I am casting no assertions on your family of course, but sons, brothers and fathers have all in the past murdered women and girls who were their mothers, sisters and daughters.

OP I wouldn't bother trying to come up with data to change your relatives mind.
If he can't see the ridiculousness of putting men in women's spaces then it's because he doesn't want to see it. I doubt some number would do any good, he may well just say 'yes, but...'

Peg this one up to a lost cause.

I would be inclined to flip it around for your male relative and ask him why he's so comfortable with the status quo of male on male violence. By insisting he and other men are unsafe to be around if they meet someone dressed like Eddie Izzard they are accepting their own uncontrollable violence as perfectly acceptable to them. Why should women be explaining, let your violence tolerating relative explain why he's happy with that.

I'm safe around my son, brother and dad but doesn't mean I want them in women's spaces.

Safety is the priority but privacy, dignity, comfort etc matter too.

Hopefully you can work out what I meant there 😂

I also included the sample size of 99. Because I don't think it's that necessarily large enough so the results should not be considered without awareness of the sample size.

Right enough, missed that

@Shelefttheweb

Yes. It's in my quote "transgender inmates". So not all transgender people

We need to be accurate - I presume this refers to the population behind bars not the whole population. So 44% of those behind bars.

The latest census also found men who identified as women were five times more likely than other men to have been incarcerated for sex offences at the time of the census.

Plus studies have found increased violence in sex offenders who were ‘chemically castrated’ (given puberty blockers) in USA. Inability to rape women with their penis made them more likely to penetrate them with instruments or attack them more violent generally

44% of male-to-female transgender inmates are behind bars for sexual offences.
The vast majority, 85%, were convicted of violent crimes that caused death “or serious harm” to their victims (58% of whom were children or women).

The study also found that 70% of the trans offenders with sex crime jackets were themselves the victims of childhood abuse.

Sample size was 99.

The study — entitled Gender Diverse Offenders with a History of Sexual Offending

Same study shows female to male transitioners adopt male pattern offending

“MtF transitioners were over 6 times more likely to be convicted of an offence than female comparators and 18 times is more likely to be convicted of a violent offence. The group had no statistically significant differences from other natal males, for convictions in general, or for violent offending. The groups examined were those committed to Surgery, and so more tightly defined then a population based solely on self- declaration”

From the study linked earlier

I can't quote the study but I learned this here so hopefully someone else can:

There is higher incidence of violent crime or maybe it was sexual violent crime among trans women (or maybe it was transgender?) than men.

There was also a study showing there is a higher incidence of suicide among those post transition than before transition. With much more robust research methods than the study saying the opposite which didn't have long enough follow up periods.

Think I will start myself a note with all the links so I can actually link in future

I think that attempting to study the small group of TW who have all the surgery and are genuinely dysphoric would be tricky. It wouldn't make sense to compare them to the wider male population as there are other factors at play (sexuality, trauma, socialisation). Do we even know if there is a difference, by sexuality, in levels of violence perpetration?

I don't think the current climate would allow researchers to separate the fully transitioned from the intact or even TW attracted to men, from those attracted to women (or themselves as women) - unless the more vulnerable group could be used as a Trojan horse for the others.

This delightful TW, both a murderer and a sex offender who attempted to rape a shop assistant, said he did it because he wanted to get surgery for free in prison.

I was going to post same link as @SavvyWavvy ... there are also more GRA documents relating to this including expert witness discussion/opinion on why violence/sex crime rates of the mtf self-identifying population housed in women's prisons are so atrociously high.

Interestingly, not one man that I have known well in my life has been aggressive or in any way a threat to women. But I sure as hell know that every person who has raped is male!

Most of those in the public sphere seem to be very angry most of the time. So it doesn’t appear to make much difference.

There have been studies and they show that trans women retain male patterns of behaviour, including violent crime.

I doubt there is reliable data on this but, even if there were, most eunuchs of the relatively recent past were castrated pre-puberty (to preserve their singing voices) so would not necessarily be informative as to the behaviour of post-op TW.
