Is It Ever Appropriate To Publicly Diss An Ex?

Last week saw a flurry of exchanges and subliminal shots between Amber Rose, The Kardashians and Kanye West himself through interviews and social media. How should celebrities handle there public break-ups and is there ever a time where it is acceptable to publicly diss an ex?

I disagree with it but these people are CELEBRITIES. It's part of their job to court as much attention as possible to promote their brand. I couldn't give two shits about these people (who you don't know and they don't know you)'s personal lives. I'm here for Kanye's music.

How does "protecting" one's wife equate to slut shaming? Isn't Kanye, Kim's third husband, though? Kanye probably knows about a few skeletons in Amber's closet, but she probably has a whole graveyard of secrets on him.

I have no issue with kanye saying what he said..Amber has continuously talked shit about Kim..but I've never once heard kim say one thing about Amber.never even said her name...but Amber still goes after her and her family..so maybe kanye sees it like.. Kim is Ambers target because of her relationship with him.so maybe he feels responsible for the attacks.so he was tryna handle it.since kim wasn't even defending herself..but she still ain't stopped..my thing is..she just broke up with her husband..the father of her child..she was with kanye..what like over 4 years ago?..but she still bitter as hell?is that really the only way she can stay relevant?..
