A short thread of my essays on Medium - mostly debunking anti-trans disinformation and other bigotry

1) "Sex-based rights" are contradictory nonsense

The term is a dog-whistle slogan, coined just to exclude trans people, with multiple meanings — none of which make sense

When survey interviewers decide what your gender is for their data, without asking you, they get it wrong up to 7% of the time.

With a significant bias towards coding people as "male".
Kim Hipwell analyses how recent parallel usage of self-reported gender with their usual 'observational coding 'in the European Social Survey highlights the unreliability of observational coding.

The European Social Survey: A Case Study In Gender Assignation
In this article, I will show that it is incorrect to assume that “observation” can be used to find out a person’s gender or sex.

The fucked up thing is this is *far* from the worst thing I've seen said about trans kids by so-called "gender-critcal" people. When Brianna Ghey died a lot of them set about trying portray her, a child murder victim, as a pervert.

New article in TSN in which I look at European Social Survey data which shows that “observational coding” of gender can create substantial errors in survey results.

The implication is that this practice is unreliable and should be abandoned, contrary to the Sullivan Review’s recommendations.

The Reform candidate at this month’s byelection claims he wants to put Britain first, but is he still on the payroll of Viktor Orbán’s far-right propaganda unit?

Now the editor is castigating her and journalism professors for not being “prepared for the workforce.”

The fact that these sentences always end with "... which we will cram with more work for them" and not "... so we moved to a four-day workweek" really illustrate the hollowness of some AI evangelists' promises that AI will deliver us to some kind of post-work utopia.
“By removing writing from reporters’ workloads, we’ve effectively freed up an extra workday for them each week” is such a strange sentence to read.

Hilary Cass here arguing for children to be prevented from being known by a preferred name or getting a haircut in case it encourages them to continue later in life to transition.

Hilary Cass acts like gender variant children should have the transness hazed out of them.

Pure moral panic. How, precisely, would a child who experiments with a different haircut or pronouns get “locked in” to a trans identity?

The parents who had no problem letting her identify as trans suddenly restrict her from identifying as cis? It makes no sense.
"if they socially transition too early we think they can get locked onto a trajectory that may not have been the correct natural trajectory for them"

It's also just not evident based. For all the evidence Cass had tried to amass, this speculation that kids who might have ceased being trans are being frozen in time rather than helped to develop their growing minds, identity and agency by exploring and expressing it actively has zero evidence.

When I worked for Reason magazine during Trump's rise to power in 2016, I was explicitly forbidden by the editor in chief from writing about Trump's racism, or the violence and racism at his rallies.

It was a "sideshow," I was told.

It’s the Government’s duty to protect all communities - including trans people.

They’re failing to do that.

The article doesn't say it and I've forgotten the specifics, but the 'change' suggested involves a statement to Parliament from the relevant minister. That's it.

This btw is a fantastic example of an opposition party acting like a real opposition party: Direct criticism and a specific alternatives.

Indiana Sen. John Petit called the phrase “all men are created equal” in the Declaration of Independence a “self-evident lie” during debates over the Kansas-Nebraska Act. Lincoln *never* forgot it, and neither did a lot of other northerners who considered the document their political lodestone.
“One dashingly calls them ‘glittering generalities’; another bluntly calls them ‘self evident lies‘; and still others insidiously argue they only apply to ’superior races.’”

There are three issues in @zackpolanski.bsky.social’s piece

1. Exposing how transphobic this Labour “government” is.

2. Showing his support for trans people when we need it.

3. Exposing the Starmer regime’s dishonesty; how they pretend to be constrained by the Supreme Court when they are not.

Zack Polanski is the only party leader not pretending that our "supreme court" is analogous to the US Supreme Court lol

We don't have a codified constitution. Nothing can limit parliament's ability legislate. Remember when Sunak passed the "actually Rwanda actually is quite safe actually" law?
