Everyone has 1 vote. The influence of that 1 vote on your life is probably smaller than that of an affectionate relationship with that relative. Imo political confrontations are better kept for the street/pub/doorstep. The unspoken agreement not to touch on the topic must come from both sides though.

I disagree, the consequences of how people see and interact with you based on that one vote isn’t separate from any other consequences the vote has.
