Just realised, listening to @thetwomatts.bsky.social pod this week, that I forgot to recommend this fab piece on Bobby J by @youngvulgarian.marieleconte.com, written before his 'another white face' schtick but very telling anyway.

Robert Jenrick, the hollow man

He heads into the Conservative conference as the stricken party’s likely next leader. But this opportunistic ‘saviour’ could kill off the Tories completely

A well known 1983 election poster

42 yrs on, the opposing view 'You can't be British/English if you're Black' is still defended. Powell & the Monday Club did then call for *voluntary* repatriation, a view the Thatcher govt rejected

Many of course disagree(d) w/the poster's claims for other reasons

LOL.

You, falsely, claimed that Canada rolled over the deal and we got *exactly the same benefits*

Alan, correctly, pointed out they didn't, and we got a worse deal - which *you yourself have admitted*

Why continue to humiliate yourself like this? .

As we came together this evening to mourn all the lives lost on and since the 7th of October, we share in the fragile hope of Palestinians and Israelis welcoming the announcement of a ceasefire and hostage deal that will see Israeli and Palestinian families reunite with their loved ones.

Netanyahu's mouthpiece, Amit Segal, casually admits on Twitter that his country has been holding 1,700 people from Gaza hostage, including children.

Among other things, according to the decision:

- 250 security prisoners will be released.
- 1,700 residents of the Gaza Strip who were not involved in the events of October 7 and were arrested after the massacre will be released.
- 22 minors under the age of 18, residents of the Gaza Strip who were not involved in the events of October 7 and were arrested after the massacre, will be released.
- 360 bodies of terrorists will be returned.

"I just think armed resistance to military occupation and apartheid is futile, no I don't support cutting off trade with Israel or imposing arm embargoes or doing any boycotts either" is the exact same thing as "I support Ukraine but wish Ukraine would give up all of its territory for peace".

It really can't be said enough: the goal of the "anti-woke" movement was always to destroy social norms against bigotry. And it worked. And there's a whole lot of purportedly "left" thinkers & commentators who helped it -- indeed, it couldn't have been done without them.

They should feel bad.

Sigh. If you can't/don't want to address the Windrush point that Stephen and others have made, fine, but why make a fool of yourself like this? Embarrassing. Let's leave it.

Jonathan Portes @jdportes.bsky.social · 1d

It's very easy to turn that round. If people are deported /made homeless because of the lack of a secure govt id recording system will *you* be saying the same thing?

Oh wait. That already happened.

I broadly agree with @stephenkb.bsky.social here.

Make no mistake. Those who spearheaded the Gaza genocide will try to relaunch it in a more ruthless manner, at the earliest opportunity.
They will fail only if there will be an alternative vision, one of recognition, life and equality for everyone.

Leunig, a former gov adviser, said scrapping it — while it would boost growth and productivity — would be “a very, very big tax cut for rich people”. One effect would be to boost house prices, making the main beneficiaries the existing owners of expensive properties in the south-east of England.

Should stamp duty be scrapped in the UK?

I hate to break it to you, but there are literally hundreds of research articles by Indian researchers with actual evidence/data on this, so maybe I might place more faith in them than your random "zero benefits" claim 😉

Goodnight.

Jonathan Portes @jdportes.bsky.social · 1d

That's presumably why the centrist and left wing opposition parties have pledged to scrap it? Like the CPI did in Kerala? Oh, wait. 😉

??? The "direction of travel" is from 2009, isn't it? And which Indian political parties have called for Aadhar to be scrapped?

Jonathan Portes @jdportes.bsky.social · 1d

Aadhar was first introduced by Manmohan Singh..(not exactly a fascist!) and its main function has been to enable access to welfare/services for poorer Indians.

Not necessarily an argument for digital IDs here but saying we can't learn anything from India is exactly what it sounds like...

Most Indian progressives are for fairly obvious reasons. They make it possible to implement progressive social welfare programs, and that's Aadhar's most important function.

Seriously? You might want to check on that. Calling Manmohan Singh a fascist is a bit of a stretch...
