Your definitions are cordially solicited. Succinctly say what a hater is. We find it a deplorable neologiam. Consider;
BREAKING NEWS 2002: "Rapper, the Nortorious F.U.K. lashed out at critics who questioned his admitted role in a drive-by shooting at a Detroit playground..."
BREAKING NEWS 2017: "Singer Elt N. Johnson blasted haters who questioned his stuffing an eggplant up the poop-chute of his adoptive son, Nerviss, onstage at a concert in Cornwhole, England last week..."
"Critic" does not imply that either party to a dispute is right. "Hater" pretty well scripts the whole following news story. We're sorry. News is non-fiction. We should have said "narrative," which is fiction being pandered as fact.
