Finally got round to giving @benansell.bsky.social's latest. It's also one of his very best - especially if you want to understand the extent to which Reform voters (often talked of as 'the people' and, apparently therefore, representative of all UK voters) are real outliers, culturally-speaking.

I've always been baffled by that. Isn't the point of ANY job to be productive for society as a whole? And yet there's this idea we only get degrees to get well-paid jobs for our own benefit and enrichment. I work in medical diagnostics supply. Pretty sure many people benefit from that besides me...

Anyone who can look at the current underfunded state of UK universities and think there's half a billion quid you can take out of the sector without doing catastrophic damage is just not fit for office.

For decades we've had "graduates pay because only they benefit" to justify student loans. This is mad. People like living in a society with doctors, nurses, architects, engineers, artists, musicians, scientists... EVERYONE benefits so the sensible, progressive way to pay for it is GENERAL TAXATION.
For more than a decade now the government’s answer to how to fund universities has been to make money from overseas students.
The last lot then tried to discourage students from coming here.
This lot just want the money back.
But then how do we fund ourselves?
Crazy.

Suggesting that science is or has “orthodoxy” is a fundamental misunderstanding.
Orthodoxy implies unquestionable dogma.
Science doesn't work like that: it’s a method designed to question, test, and revise if necessary.

Breaking News: Robert F. Kennedy Jr. said he personally instructed the CDC to abandon its position that vaccines do not cause autism. The move underscores his determination to challenge scientific orthodoxy — in this case, that vaccines save lives — and bend the health department to his will.

In an interview, Health Secretary Robert F. Kennedy Jr. cited gaps in vaccine safety research. His critics say he is ignoring a larger point: Vaccines save lives.

Looking forward to being denied services due to my "appearance" because of the transphobia of a few vocal hate-filled bigots who dare to call themselves feminists!

Fixed it for you. Idiots! If the exclusion is based on appearance then it will certainly impact cis folks as well as trans folks.

The party that promised "free speech on campus" has made sure there can be no free speech on campuses.
This week, I withdrew from a speaking engagement at a public university because they sent me a list of prohibited “words & concepts.” I will not humor this censorship. It does a disservice to the stories I’m discussing & the audience, who deserve unfettered access to information & conversation.

So counter-productive. Use dishonesty to aggravate feelings of grievance over asylum, and respond to the problem you create with performative cruelty.
The Home Secretary says "we have become the destination of choice in Europe, clearly visible to every people smuggler and would-be illegal migrant across the world"
That is a factually untrue claim: the Home Office shows that the UK is fifth, getting 1/10 claims, while Germany gets 1/5 claims

Late to this, but if the Sunday Times is correct that Morgan McSweeney spent one and a half hours last week with Lord Glasman then he isn't fit to fill any senior position in government.

Everything about the current 'debate' around this is dismal, not just morally but because it is so stupid. For example:
It conflates asylum-seeking and illegal immigration (and sometimes with migration generally)
