I wouldn't really call it "harassed", I think she recognized him as either Brandon or Brody (lbr they could almost be twins) and wanted to know if it was really him without saying the wrong name. She obviously could've been a bit more sensitive with her wording but I don't think she was being hateful, especially judging by the end when she laughs and says "I don't..." -- she was probably apologizing. But wasn't her wording correct anyway? Didn't Caitlyn say that she's still her children's father?
Anyway, the video is still funny
