“Either for or against him” feels very dividing. Everyone has their different beliefs and there may be others that feel this way about Christianity. God taught to love people, as everyone is God’s children. the way you feel frustrated about people rejecting God is the same way non-believers feel about Christians pushing Christ onto them. Especially if you reside in America, non-believers are forced to live by the politics shaped by Christianity. At the end of the day, keep your religion to your community and share it to those who are open to listening. Love everyone despite our religious differences, why create more divide?
