Wonderful for you.
I would always keep away from politics, Brexit included- at family get togethers - sadly other members of the family would not- so best to avoid at the moment with them.
I am only reporting what youngster expats here have been saying about dreading visting parents and other leave relatives (mainly old aunts and uncles)- as they fear they will not be able to keep stumm- this especially if their lively hood abroad, their jobs, their research grants, etc, etc, are at risk.
None of you ahve responded- how would you feel about sharing the table with vociferous Trump supporters, who will talk abut Mexicans being rapists, how he wants to massively add to the nuclear arsenal to frighten Putin and Kim Jung, and the like. Would you feel comfortable when they mention how Obama is a Muslim AlQuaida supporter and spy, etc, etc.
