Black text on white background 
"This day is profoundly painful for so many New Yorkers. It marks three years since the horrific war crimes of October 7. On that day, Hamas killed more than 1,100 Israelis and abducted 251 others. We grieve alongside our many friends and neighbors who still carry that unthinkable loss.
 
The suffering did not begin nor end that day. It instead continued through the Israeli government’s devastating, ongoing genocide in Gaza, in which it has killed more than 74,000 Palestinians—including more than 21,000 children. Even since the so-called ceasefire, more than 1,400 Palestinians have been killed. That suffering has intensified with every Israeli bomb dropped on ambulances waiting outside hospitals, every drone strike targeting a residential building or journalist, and every shipment of food aid turned away at a border crossing. Many New Yorkers are reckoning with this unbearable grief, and we mourn alongside them – all while knowing that our tax dollars fund these war crimes.
 
Three years later, we must refuse to accept a world in which occupation and apartheid continue, where war crimes are met with impunity, and our federal government continues its complicity with every arms shipment.
 
To honor the dead, we must fight for a world in which every person can live with freedom, safety, and dignity."

Opposition to Israel never "spills over" to antisemitism. It may be embedded in antisemitic worldview to begin with or it isn't antisemitic at all. This metaphor of "spilling over" is unhelpful as it suggests the problem is excess.

Remigeration, deportation & dehumanization of immigrants is extremely popular in Europe. Frontex has directly played part in drowning of countless immigrants in the Mediterranean with our taxes. Europeans just hate Trump particularly, not his worst policies. They support those locally.

We would all have better conversations about Zionism if we viewed it as a nationalism like all others, akin to diaspora Serbian nationalism from Canadian Serbs. Not a civil rights or social justice cause, but also not a way Jewish people are abnormal or ontologically evil.

@chefjoseandres

© Translated from Spanish by Grok
Incredible to see the "experts" on resolving the housing emergency that Spain is experiencing! On every television! @telediario_tve @ANoticias
@tele5_noticias @noticias_cuatro The reality is that we have politicians who try to create decrees and solutions when they lack the preparation or knowledge to devise a real solution to the problem we're facing.
Spain doesn't have a problem of a lack of decrees. It has a problem of a lack of housing.
And as long as the Government keeps confusing announcing measures with solving problems, we'll keep paying the consequences of its inaction.
Subsidizing demand without increasing supply pressures prices. Regulating a market more and more without building new housing doesn't eliminate scarcity: it manages it. Taxing a type of rental can change incentives, but it doesn't lay a single brick either.Because housing doesn't get cheaper by distributing scarcity. It gets cheaper by ending it.
Spain needs to build. A lot.
More available land. Permits in months, not years. More density wherever possible. Legal certainty. Much more public housing and also private housing.
But the Government isn't doing what's necessary. It prefers to intervene on the few homes that exist rather than create the conditions for there to be many more. It prefers to present patches as solutions and load the cost of its failure onto owners, developers, and citizens.
The rest can serve to redistribute, protect certain groups, or change incentives. But let's not confuse that with solving the underlying problem.
You don't fix a lack of housing by better distributing the few homes that exist. You fix it by making many more exist.
Less propaganda. Less patches. Less obsession with intervening on the same apartment.
More supply. More construction. More homes.
