False: It is possible to work against ideas and actions which run counter to your own without hating the people who espouse and act upon them. For example, I can love and feel compassion for the person who created this meme, even though I feel its underlying philosophy is generally responsible for all violent conflict and the fear and hatred it engenders is routinely used to drum up support for war mongering.
What is not possible is to bring light and love into this world under the guise of hatred, intolerance or a self-aggrandizing sense of moral superiority.
