I have faced this issue before. One family member just KEPT talking about a particular group of people, calling them all out of their names and making ridiculous generalizations about them. And I finally just told this person, “Listen, the next time you make a comment about this group, I’m walking out the door.” I can’t change your opinion about this particular group, but I don’t have to be a listening ear to the bullshit. And we mutually agreed that those discussions were off the table. And when I was challenged, I stood up, put my shoes on and literally walked out the door.
