I am sure that all expatriates living in the USA are running into this problem. You go home for the holidays and all your relatives and friends want to discuss is Trump.
- Does he really mean what he says?
- How much support does he have?
- What do you think?
Unfortunately, you have to explain that yes, he is for real, he has supporters (I know some), and he represents the worst of America. Then you try and change the subject to something more pleasant like your recent colonoscopy or the service on US airlines.
