Someone I know through an acquaintance sent me a friend request on Facebook. We are not friends but I do see them at a mutual weekly sports event so I accepted. Now my Facebook feed is filled with their far right racist memes! I could just unfollow and keep the peace but am tempted to unfriend to make a point. He will ask why. But ... he's one of those guys who is so stupid there's no arguing with him, he just doesn't understand! So, quietly unfollow or unfriend and tell him why when asked?
