I hate nationalism very much and would love to have a more global hub to learn about the important political subjects that dont crop up that much in French (my local one) or US media. Sadly, I never see such a thing. National communities are a bad solution but to a very real problem, which is that global themed communities end up being US ones.
This strikes me as they key point. While I seriously doubt any community based on where I live (Belgium) would be very active, it would be really cool to have conversations about things happening near (or near-ish) me or about region-specific subjects.
The example you give about immigration is a really good one, since the challenges with the EU’s border regime are meaningfully different to what the US is facing.
No idea what the best way to approach this.
Country-specific communities chafe ideologically and might just not be active enough to be worthwhile. Language-centric ones make some sense, but run the risk of seeing the same problem as English ones (namely, being mostly centered on discussion about the largest or most culturally dominant nation state using that language). It’d also (potentially) divide countries that aren’t linguistically monolithic.
My local anarchist collective has already decided to donate and is currently looking at how we can do additional fundraising.
