Asking out of interest.
If you meet (in the UK) someone who is an immigrant from a country which is rotating non-stop on the "breaking" news due to something really bad - a natural disaster, war, famine, refugee crisis etc.
Not a close friend, a new casual acquaintance - say a friend of a friend that you met at a birthday party or something like that. Would you take initiative to discuss the topic with them / offer your interpretation or thoughts on what is going on? If they did not bring up the topic itself? Is it polite to show interest or quite the opposite?
