I'm not sure that will be interesting for you, but cross checking rational arguments with emotions seems to have support from the evolutionary point of view. Emotions may be a 'superordinate mechanism' coordinating memory, attention, energy allocation and other information-processeing mechanisms.

Of course, as with all evolved features, there is a question about the delay. Our culture is changing faster and faster. Our emotional software may be outdated. What then I don't know...
