True enough, but friendship trumps political difference time and time again. As it should. Remember Ronald Reagan was Married to a leftist, Jayne Wyman, and Bob Hope him self stared with and was friends with many actresses that had left leanings. That doesn't make him one.
Jane Wyman was not a leftist.
We have gone too far when friendships are shredded because of politics. One of the classic friendships that endured was Jimmy Stewart/Henry Fonda, both of whom served in WWII, but whose offspring went in different directions on VietNam. They stayed friends to the end.
