Protectionism, Fascism, Nationalism are cousins

It is feared that world economy is moving to protectionism. This is shown by American fiscal stimulus bill provisions for buy American. I would like to equate this to Fascism or Nationalism and also explain why Nationalism will one day lead to regionalism and casteism and all kind of hate between people.

When you protect American interests you are caring people in one region distressing countries which are exporting to America or the country that is showing protectionism. This is very close to Nationalism that is shown for example fascists in India. This nationalist financial protectionsim is closer to the regionalist financial protectionism shown by MNS - regional nationalist Hindu party in Mumbai. (In Mumbai these parties wanted jobs to be reserved for locals)

This nationalism can easily mutate to the regionalism shown by MNS in Mumbai - Attacking Biharis from the poorer parts of India. Soon you will have one region turned against another, one caste turned against another. Once you detonate the nationalist bomb (hate, fear against a community/nationality), you will never have control over it.

People who support and confuse patriotism with Nationalism should realize that Nationalism can easily mutate into other dangerous cousins that will be very difficult to cure. If you see India now you will realize what will happen when you elect a fascist party like BJP to power. (I always avoided naming the party directly, but I think it is time that people talk about it as that party is not just another party)

America should stay away from protectionism, India should stay away from nationalism and regionalism its side effect.
