What things look like or sound like doesn't really matter. The Bible tells us to preach the truth rather than the fluff. If you think an Arminian-sounding gospel and dynamic in terms of how people interact with God is just what things look or feel like then you should simply preach the truth instead, the truth that you actually believe in. I've preached hell to hardcore atheists and others and seen a few people take up the faith after conversations that included that. So there is no point in placing "mushy love" on the Arminian side and "fear of God" on the Calvinist side.
