This is obviously not what I am referring to when I state the opinion that people who demand pre-nups because they fear the failure of the marriage are in denial of the fact that in the vast majority of cases, there are no outside forces that are going to come raining down from on high and destroy the marriage, there are only two internal forces; you and your partner. Anyone wanting a pre-nup is refusing to acknowledge their potential part in the break-up, should the break-up occur, and basically saying "if our marriage craps out it won't be my fault, it'll be yours, and you are the one who's gonna have to suffer for it, not me."
Of course there will always be exceptions, but most marriages break up because people choose to walk away from them. Even when disaster like illness strikes though, people still choose. As I said before, if it isn't ended by death, it's ended by choice, and it takes two people to make that choice. I don't really see any realization of this from those who cry "I've been screwed before and I'm not gonna get screwed again". Best not to get married if that is your view.
