Marinate:
Talking is over-rated. Let the burden of talking fall on others. Focus on LISTENING, even if you strongly disagree. You WILL NOT convince another family member to abandon their viewpoint and adopt your opposing perspective. Instead, show curiosity and – radical idea – KEEP THEM TALKING:

“Say more about that. What do you mean we’re losing our traditional values?” You lose nothing by listening. It doesn’t mean agreeing.
