if the situation is still salvage'able, highlight the common joys / values which are still shared among you all. gently remind them of the shared right to hold their own views, and still be connected. their right to enjoy that "your opinions are yours" freedom is naturally yours too.

or just tell 'em straight up that you miss them and value them. that we all make mistakes and misjudgments, and subject is not important enough to be worth harming your connection to them. "you really matter to me" is a powerful message!
