Even if a community did have a higher homicide victimization rate than average, it could still punch well above its weight in terms of Twitter mobbing.

Even if I ceded that trans people are uniquely online and 'too strong' on twitter, and I additionally cede that somehow that also means 'they' (and not a few individuals) are uniquely willing to kill their own in the name of internet points, that doesn't change the fact that the group is currently marginalized, and 'wins' online don't actually translate to acceptance in the real world.

You needn't look far to find laws being passed that specifically target and exclude the trans community.

Painting a marginalized community as vicious enough to 'eat their own' paves the way for very ugly rhetoric that we've seen with other marginalized groups the world over. Chappelle especially is smart enough to know this.

And indeed, from reading the comments here and elsewhere, it seems that whatever empathy he attempted to bring to the special, the modal comments on his work looks like this:

'I prefer the old skinny Chapelle. Black white supremacist is a killer. However, I must confess, I agree with him and J.K. Rowling on this one. Being trans women doesn’t make you a woman.'

The HN sentiment above this comment seems to be 'wokeism' is destroying the fabric of America, trans folks on twitter are 'woke', and bullies, and the real problem.

I don't think anyone is disputing that trans people disproportionately struggle with mental health issues and suicide.

I don't dispute it, but also, I think being kicked out by your family, not being able to get a job, having poor access to (or being afraid to ask for) healthcare, or being assaulted, etc... e.g. the effects of being marginalized, have a dramatic impact on mental health even without considering what it's like to be trans in isolation. I've met many folks(trans and not) in situations like this and the despair can be palpable.

This review seems to be speculating in the same direction: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7317390/
Furthermore, compared with trans men, the societal position of trans women is lower (31, 32).
In the Netherlands, between 1972 and 2017 suicide rates showed a fluctuating course. Our finding of a slightly decreasing suicide risk in Dutch trans women may confer some hope. Recent studies showed an increase in societal acceptance toward lesbian, gay, bisexual, and transgender people (31), and indications of an increase in social‐economic status over the years (33).
...
Although the literature on suicide risk factors is comprehensive, and particular suicidal risk factors like verbal victimization, physical and sexual violence, and the absence of social support (9, 34), may apply for transgender people in all stages of transitioning, it seems clinically highly relevant to understand and explore possible differences in motives and risk factors in the different stages of treatment.

Race and gender are fairly easy to track because they get marked down on various forms of ID

It's my understanding that changing gender and name on ids is quite common, but often legally fraught. That kind of change effectively serves as as 'trans/enby: Y/N' where it is allowed at all. But yes, I don't think putting that explicitly on an ID is a safe idea.
