What do you think about people who give the silent treatment as a way of dealing with conflict?

my father and I often get into arguments about our differing beliefs on certain aspects of life. Often when I don’t agree with what he says, he just gets quiet and says nothing. Sometimes his silence never ends. I find this to be really rude. Like he is saying it is either my way or the highway.. What do you think of this ? I am 28 by the way.
