I know you don't have to accept every argument you are invited to...but my goodness do people get feisty when you don't!
My friend, it's fine. I differ in opinion from you, and for fundamental values/experience/personal reasons I won't be shifting to your side.
It's ok. You'll be all right. Life will move on if I don't think you are the most brilliant shining light in the universe, who is the be all and end all on this topic.
It'll be all right.
