Why in the hell are the King children fighting?

Everyone knows Dr. Martin Luther King and what he did for civil rights and the rights of all people, not just people of color. Coretta Scott King was his rock and it was my honor to stand out in the rain for hours for the opportunity to view her at Ebenezer Baptish Church when she passed away. So can SOMEONE please explain to me why their three surviving children (Yolanda died last year) are ackin' a fool? Martin and Bernice sued Dexter the other day and he returned the favor by suing them yesterday. Kids, please get together and work it out.
