Hei Geoffrey! Kanskje de er ikke gal, kanskje de bruker snarveier når de snakker om fluor, regnvann og 9/11? Hva som du skriver, ser ut ikke så galt... from what you write, your hostfamily seems like people who have read up on current and past events and have an opinion on them, which doesn't seem so strange from the context of what I've heard around dinner tables in France, or elsewhere in Europe, and it seems quite mild compared to most comments you might read on the internet. As an example, I'm not sure where you're from in the US, but do you know much about water rights in the Southwest? How in Colorado, it was illegal to collect rainwater --and since 2016, citizens can only collect 110 gallons per year? https://www.washingtonpost.com/blogs/govbeat/wp/2015/03/24/it-is-actually-illegal-in-colorado-to-collect-the-rain-that-falls-on-your-home/ ...as for 9/11, you can probably join them in their analysis of why the US invaded Kuweit, no? They sound like nice people, a good cook, and a carpenter, and dinner conversations must be interesting. :)
