I would love to see an ActivityPub implementation of a decentralised library of things. You could post things you have and like to lend, add location and availability. Others could comment, like, boost and inquire.

Edit: of course trust is a huge part of it. But social media (friends of friends etc.) is the perfect fit imho.

As a native German and antifascist leftist I’m worried as well, but I don’t think that history will simply repeat itself. The problems we are facing are very different and I don’t think that a party as radical as the AfD is able to gather 20% support in a federal election. Germany HAS become a multicultural wonderland in recent years and the majority supports it! German politicians of the left, center and center-right shouldn’t engage in the blame game. Especially the CDU/CSU has to understand that their role now is not to copy AfD talking points.
