One side to emotions is that they are seen as qualities dictating behavior of women and children. She is irrational and crazy is not rare a thing to hear. Statement which justifies ill-treatment and putting down a second class citizen.
http://unu.edu/publications/articles/the-role-of-emotions-in-politics.html According to study by Jonathan Mercer of University of Washington concepts nationalism, trust, justice and credibility when stripped out of emotion appear unrecognisable. This is very clear. Concepts such as trust and justice work in building nations self-evidently and become parts of our identities(more or less) for us to form groups of power. To have trust is to build a nation and make politics. Politics is where people should be trusted, but over and over this trust is failed. In keeping nations together there is a certain amount of pride, patriotism, nationalism, love for the country and its people. Mere emotion. Nationalism nor patriotism do not tend to show as the most rational of ideologies. They follow feeling. We are like this and we like us as we are. We want to protect ourselves to stay as we are. We can continue to be afraid of change, immigrants, strangers, oddities, settling for traditions and wanting to stick with people of our kind. Reason does not have much to do with all this. Most sensible thing for people to do in order to evolve is to expose oneself to new things, new ideas, all kinds of people. Surprise is of course how people who think are very clever can be so narrow-minded. This happens within universities as in working class circles. Isolation is not out-of-order. It is a norm. http://www.3quarksdaily.com/3quarksdaily/2011/02/the-six-emotions-of-revolution-what-egyptians-are-feeling-now.html
