One of the Chevra: “Rabbi Avigdor Miller Z”L was once asked “What do you think of certain groups of people who believe that only their beliefs are correct and only the way of life they chose is correct, and everyone who disagrees or acts differently is wrong?”
Rabbi Miller answered ” That is the way it should be!” if you believe something is right or you chose a way of life, hopefully you think that your beliefs are correct and your way of life is the correct way, and anyone who believes otherwise is incorrect!””
I agree with this! The idea that there is no such as absolute truth is a goyish, western one.
