If we have any goal in dialogue, (with Muslims and others) it is to convert ourselves, not the other person. No one is moved unless we ourselves are moved. Dialogue also means no Muslim bans. As for God not needing protection from us, this is not only about not needing to protect His honor (as ISIL and some Trads attempt to do), but is also about who morality is for. God is perfet, He does not need us to be moral for Him but for ourselves for a better life here. 
The Pope’s Sunday homily, which every priest should have given, shows us that worship without love for our fellows is hypocracy, with this love including charity. What is charity? Is it making others behave? I think not. Is it opposing the efforts of the state to do justice and charity? Again, Jesus preached a social kingdom of God, so no.
