Thank you for the two links.
Unfortunately, I do not think they assist.
The 'study' you refer to asks, "To what extent do trans people and cisgender LGB people experience different levels of discrimination and violence?" This does not address your claim regarding the difference between the comparative risks faced by transwomen and women.
The 'study' [my bolding]: "The EU LGBTI Survey II (FRA, Citation2020), collected in 2019, is the largest cross-national survey on the experiences of lesbian, gay, bisexual, trans and intersex (LGBTI) people across Europe. Deployed as an online, anonymous, opt-in survey, participants were recruited via both online and offline channels in 30 countries. Participants completed the questionnaire in their native language (for more information on the translation process, see FRA, Citation2020). The sample consisted of self-identified LGBTI people aged 15 or older..."
Even if this were what you call a "good" study, there is no comparison/control to show the difference between transwomen and women.
Your other link, the CPS "watching brief" states
- Research indicates that 62% - 73% of transgender people have experienced harassment and violence because they were identified as transgender. This included verbal abuse, threatening behaviour, physical and sexual assault.
The percentages mentioned here will be vastly inflated by the inclusion of experience of [undefined] "verbal abuse" - as this will almost certainly include misgendering (otherwise known as correctly identifying the sex of an individual). Does this come under your definition of 'harm'?
There is no control. For your assertion to work, what evidence do you have that fewer than 62% - 73% of women have experienced harassment and violence because they were identified as women?
Neither link evidences that transwomen are at a greater risk of harm than women, which is what you claimed.
