Die mythe dat Nederland zo rechts heeft gestemd en dat er 'dus' over rechts moet worden geformeerd, nu ook weer herhaald door #Eva zelf. Wat is dat toch?

Als je centrum en links bij elkaar optelt, kom je óók op een parlementaire meerderheid.

FOX: Here's a viral video of landscapers who were being addressed by a CBP agent. What do you say to people who say that falls outside the purview of getting criminals out?

GREG BOVINO: Martha, do we know the criminal records of those so-called landscapers?

Israëlische soldaten en -illegale- Israëlische kolonisten slaan een Palestijnse boer in elkaar die zijn eigen (!) olijven wilde oogsten. (Nahalin, bij Bethlehem)

Starting a new book - 38 Londres Street by the brilliant Philippe Sands - and this is the epigraph.

As pressing as it was in 1577.

Every now and then I go back and read the Citizens United ruling to see if it is as unhinged as I thought, and every time I do that I see it is actually far more deranged than I remembered.

‘It was worth all the suffering in that damn place,’ zo schreef een Philips-topman over zijn tijd als reservist in Gaza. Vorig jaar vocht hij mee met het Israëlische leger in Zuid-Libanon waar volgens een VN-commissie oorlogsmisdrijven zijn gepleegd. Toch blijkt vervolging in Nederland moeilijk.

In zijn boek 'The Palestine Laboratory' waarschuwt Antony Loewenstein dat het kwade etno-nationalistische ideologie van Israël ook in het Westen steeds meer in de mode raakt. 'Israël verkoopt zich als een land dat kan helpen of ideeën kan aanreiken om jezelf en je identiteit te beschermen.'

Dit filmpje van de markeronline 👏🏼 Goed gedaan.

Het maakt helder hoe mensen gehersenspoeld zijn door het telkens herhaalde onzinmantra dat asielzoekers overal de schuld van zijn. Met feiten hebben ze niets, want ze hebben van extreemrechts een zondebok gekregen.

To be clear, there are no data that provide a link between short-term use of Tylenol during pregnancy and autism. In fact, one of the best prospective studies w/ sibling controls, if anything, pointed to a protective effect for use less than 7 days

Built in the 13th century. So that mosque stood for 800 years with every sort of person from every place and every religion in the world passing through Gaza century after century, only for it to be blown up by some shithead loser sitting behind a computer that we probably paid for.
