We should define what is hate and hatred: quite surprisingly for the the Webster's , Hatred is only
extreme dislike or disgust
While for
Hate it attaches a psychological connotation: intense hostility and aversion usually deriving from fear, anger, or sense of injury
Wikitionary instead gives for Hate the same definition of Hatred given by the Webster: extreme dislike or disgust
But I would say that by the current dominant culture Hate would be defined as "irrational unjustified pathological impulse of violence",
by which the "extreme dislike or disgust" are not legit inclinations;
as we are not anymore allowed to dislike or disgust something on our own -- the dominant culture willing to suppress our instincts, our nature, which must be substituted by dictated unique implanted cloud thinking.
Sticking to the bare definition of Hate as 'extreme dislike or disgust', I'd note that eliminating such moods implies the decadence of a civilization;
as deprives the human being of a fundamental vital instinct that moves us towards beauty and order and justice.
Its removal resulting in
forcing people to accept what they strongly dislike and disgust.
In the end it's a step forward in the direction of the dehumanization and transhumanism.
