Umberto Eco said this quote
“ We need an enemy to give people hope. Someone said that patriotism is the last refuge of cowards: those without moral principles usually wrap a flag around themselves, and the bastards always talk about the purity of the race. National identity is the last bastion of the dispossessed. But the meaning of identity is now based on hatred, on hatred for those who are not the same. Hatred has to be cultivated as a civic passion. The enemy is the friend of the people. You always want someone to hate in order to feel justified in your own misery. Hatred is the primordial passion. It is love that’s abnormal. ”
