the BBC is institutionally transphobic so they're lying to make transphobes look good.

The BBC News at Six is highly misleading. They present the story as if the bigot has won the case, which is false. To make matters worse, they end with their editor reading a proclamation β€œof the Supreme Court” that is entirely incorrect.

(And, as the lecture points out, something that happens every 10 million hours might seem impossibly rare - but if you have e.g. 250 million vehicles driving an hour per day in a country, such events will happen multiple times per day)

"...Catastrophic events happen to individual systems so infrequently that it's likely that no-one on the team has seen, or heard, of that type of event, much less experienced it in person. However, these are exactly the types of events that do cause catastrophic failures in the real world."

More than that, his crew threatened to open fire on the murderers. He rescued civilians, returned to base to refuel, flew back, and rescued more civilians. Then he denounced the crimes to his HQ.

For all this he received death-threats throughout his life.

Let me just say: I have run more than a dozen marathons and an ultramarathon and I have worked 13-hour days in a cornfield in the scorching-ass sun, and none of those things broke me like breastfeeding.

I keep thinking of Beth Upton today, who won against an absolutely foul, racist bigot, and should be having the best day, but is still being monstered by our entire media, for the crime of merely existing as her authentic self and doing a job in the NHS that helps people, all day every day.

A post from ViperThreat: 

Worked as an on-call computer tech for about a year, and I've seen some weird shit. Plenty of Hoarders, elderly men with interesting sexual fantasies, Multimillonaire Lawyers with closets full of gay porn, etc.
The weirdest one was this cool old dude who had retired and lived in a double-wide trailer in a fairly nice retirement trailer park. His house had one of those trains that traveled along the walls from room to room, occasionally poking through walls and such. The primary purpose of this train was to carry his bird (a blue macaw IIRC) around the house.
From his explanation, the bird had some birth defects and had difficulty flying, so they built the train for the bird to cruise around the house on.
This may not sound all that weird to you, but let me set the stage for you:
You're a college student removing a stupid browser hijack from some old guy's computer. You're nearly done with the job when you hear a clacking sound and look up to see a toy train crossing your vision. Aboard the train is a decently sized bird that makes eye contact with you and says "choo choo motherfucker" before disappearing into the next room.
One of the most surreal moments of my life.

one of the main reasons trans healthcare moved away from strict gatekeeping and toward informed consent & GAC is that trans ppl who were denied the means to transition would simply seek it out elsewhere

Our media's reporting of trans issues is poisonous, unhinged, a betrayal by those who pretend to report impartially, and shamefully reminiscent of other hate propagandising throughout the last century. I'm surprised to see it in the UK but I need to learn that it is, since Brexit, just who we are.

You'd never know it from these headlines that she lost all her claims on the actual substance of the case, claiming that trans people must be banned from bathrooms.

Transgender is a mental virus. It's `Body Integrity Dysphoria` wrapped up all pretty for people to think it's okay and normalize it.

In fact, the ET said what Peggie was arguing was incompatible with the decision in FWS, where the SC emphasised that their interpretation of sex under the Act would *not* disadvantage trans people.

Mini thread on the ET decision in Peggie

Top line: It says exactly what we have been saying for months. The decision of the Supreme Court was not to turn the Equality Act 2010 into a nationwide bathroom ban - regardless of how anti-trans organisations have sought to misrepresent the law.

My thread earlier focused on the discussion re. FWS - but I just want to draw this out really explicitly:

The press absolutely monstered Dr Beth Upton in the most appalling way – only for the Tribunal to find that Beth had done nothing wrong, but that Sandie Peggie had harassed her.

Screenshot of a paragraph from the judgment, with the final sentence highlighted:
β€œ797. After that comment the court explained that a person with gender reassignment as a protected characteristic could pursue a claim of direct or indirect discrimination, or of harassment, if the circumstances so warranted. There was no qualification to it to the effect that that was not applicable in, for example, the context of a single sex space under Part 5 of the Act. If their decision had been that all trans persons must be excluded from the changing rooms or toilets for the sex they identify with because it was not the sex assigned at birth, and may also be excluded from the changing rooms or toilets of their biological sex, that in our view certainly does impact on their rights under section 7.”

Today’s judgment in the Sandie Peggie case says exactly what we have been saying – For Women Scotland does not require a trans bathroom ban:

Sandie Peggie harassed Dr Upton, not the other way round.

Two ways to read this. One is β€œshe lost on every substantive claim, completely failed in her attempts to ban trans staff from the workplace, and won mild procedural victories against her employers handling of her case”.
The other way is, I guess, β€œpoint one is longer so it must be more important”

I think at this stage we should point out: kicking up a huge legal fuss, losing hugely on all the merits, and playing up a ruling in your favour over a minor technical or procedural point, is a well established strategy in the UK *because* the press will absolutely 100% play along with it.
