Last Xmas, because my better half is the daughter of Iowan farmers, and we spent the holidays there (no alcohol, no sleeping in same bed; she's 35 and I'm nearly 50 btw) I had the opportunity to try. In between the "why can't you understand that Brexit must be good for your country because of refugees", etc, etc, I'm afraid I didn't get very far.
That said, these are good people, but just deluded - possibly through being exposed to social media bubbles for the first time. They may be my in-laws soon, and I didn't want to alienate them by being a smart-assed pinko Brit. And believe me, when you're travelling to church in the back of a Chevy pickup with a lot of geezers in overalls, with shotguns, that's not a comfortable idea.
