Why does the government of 1984 program the 2 Minute of Hate? if our society had this "2 Minute Hate" what would be in it? why would they have this?

Certainly,
the idea of a government ordained "2 Minute Hate" is a frightening one.  I think that
a modern version of it would be filled with identifiable "enemies" of the government,
or individuals that the government believes are forces that seek to subvert the government.  In
some weird way, modern governments do this.  Many governments manufacture and repeat supposed
threats multiple times in different manners and representations to convince the body politic of
the imminent threat surrounding them.  It helps convince the public of the need for action and
in complete faith in the government and its directives.
