lemong : 'if they really are saying this and meaning it ( as opposed to boasts on social media) then what stupid crass people they are.
Leaving the EU is a political decision...'
your comment is very naïve. It depends very much on what is being said, re immigrants, for instance. Depends very much if it turn out not to be a 'political' decision, but one based on prejudice and unjustifiable opinions, and 'non-facts'. Imagine a family, well settled abroad, doing well, kids totally integrated, speaking 2 or more languages - and the parents opinion and vote puts the happiness and freedom of that family at risk of having it all taken away - why would being angry and very disappointed be 'crass'.
If parents can argue sensibly and reasonably, giving political based arguments- then I think most would be able to 'agree to disagree'. In many case- this is not the case - arguments given make no sense and said parent will not listen to any other side or even fact- and in many cases, the arguments have shown just blatant stereotypes and prejudice. Just depends on 'how'.
