The one post I could find on Blue Sky about Selma van der Perre.

She visited the Dutch school in London every year to share her incredible story and meet the children. Her last visit was only a few weeks ago.

May she rest in peace. ❤️

Morgen jährt sich die Befreiung von Auschwitz. Ein ehrliches Gedenken beinhaltet auch den Blick auf Auslassungen im Erinnern. Jüdischer Widerstand gehört dazu & deshalb heute ein Buchtipp von mir. Rezi im Blog:

Auf dem Bild liegt ein Buch auf einem sonnenbeschienenen Stück Erde. Vereinzelt liegen gelbe Blätter im oberen Teil des Fotos, auch einzelne Grashalme sind zu sehen. Das Buchcover zeigt ein Schwarzweißfoto einer jungen Frau mit dunklen, lockigen mittellangen Haaren, die einen Hosenanzug trägt und in beinhohem Farn steht. Der Titel des Buchs lautet "Mein Name ist Selma", etwas kleiner steht im Untertitel "Erinnerungen einer Widerstandskämpferin und Holocaust-Überlebenden". Die Autorin heißt Selma van de Perre. Erschienen ist das Buch im btb Verlag.

Citing the worrying poll, but not the papers debunking it. Perhaps a wrong choice?

Support for vaccinating kids against infectious diseases dropped from 81% in 1991 to 51% last year

We are getting dumber as a society

I agree 👍

Florida bans "The Diary of Anne Frank" in school libraries. Whoever made this decision should have to eat every page of that amazing book, page by page.

Dear community, last time you helped us reach lots of new BlueSky followers. Now that we see that there is an exodus on X, it is important that these people can also find us on BlueSky for all necessary updates about Ukraine.

Would you like to share this message, preferably with a quote? Thanks!

My Retrospective on Wokeness in detail! Blogs are for just saying stuff, after all. So here is my attempt to say what was distinctive (if anything) about a recent era of socio-cultural life, what (if anything) changed, and what (if anything) was to the good

AI brain rot 101. Or is it 404?

Let's see who can resist the rot 😅.

I had no clue about either the meme or its origin. Different bubble I suppose?

Derek Groen @whydoitweet.bsky.social · Jul 17

I agree. I actually do not think they should be allowed to work full time, so you can draw my conclusion from that in regards to voting 😅.

Derek Groen @whydoitweet.bsky.social · Jul 17

If they can do so full time and legally, then they deserve a vote too.

Derek Groen @whydoitweet.bsky.social · Jul 17

16 year olds can work, so they should be allowed to vote. Sounds simple enough to me.

I really don't understand why the majority would disagree with this.

In Nederland is het vrij makkelijk om van school te wisselen.

Hoog/laagbegaafde kinderen in een thuisleeromgeving met 1 ander persoon plaatsen gaat ze echt niet helpen op de lange termijn.

Als alle slimme kinderen thuisonderwijs gaan volgen, wie blijft er dan nog in de klas?

Thuisonderwijs is een slippery slope... uiteindelijk wordt iedereen sociaal geïsoleerd en kun je samenhorige politiek wel vergeten.

As I was saying, I don't agree with that narrative anymore. But thank you for reiterating that rationale.
