I told my younger lib Brother that the only reason we get along is because I withhold my opinions for the sake of our family. Any time I’ve shared facts contrary to his indoctrination, it’s turned into months long rifts where we don’t talk at all.
And in too many families that is the dynamic. The leftist feels perfectly entitled to spew any garbage they want with the expectation they will be listened to. While conservatives know what will happen to the family if they speak the truth and question their leftist relative keeps quiet for the sake of Christmas, Thanksgiving, mom’s birthday, etc. So the Left wins. In our family it is no politics when Leslie is here. Doesn’t stop Leslie.
When I told my DIL she could express any view she wanted as long as she respected my right to do the same, she stopped talking politics rather than afford me the respect to have any opinion different from hers.
