How do I deal with this situation?

I confessed recently to my parents and my teachers that I don't belive in peace and I don't want it happen. I belive that we need ememies and we need conflicts to create "life", otherwise we would never have history and storys to tell or lessons to learn from. I belive that we should be in a utopia when we die and go to heaven and not while we are on Earth and have so many things to learn from. My parents and my teachers got really upset when I told them this, they thought that I liked war (not true) and that I was goth and or in a depression. My mom told me that I was being foolish and that I should support peace, I told her no because I don't belive in it She got really upset. My teacher dosn't like me anymore and I'm really upset that people are dissowning me about my opinion. How should I deal with this?
