South Korea is unique, and complicated.
Pentecostal: 30% evangelical Christian, with a strong pentecostal character to the evangelical churches.
Buddhist: 30~40% Buddhist, with at least 1000 years’ tradition of resistance to authority.
Confucian: that was the state “religion” for over 500 years, to the suppression/repression of all others.
Fascist: which of the Asian “tiger” economies isn’t at core, a remarkable – and somewhat depressing – realization of the fascist fantasy: state capitalism with majority-consensus-driven (and minority-oppressing) politics?
Republic: yes, the democracy seems to sort of work, here, although I’m personally convinced it’s a lot more fragile than many analysts seem to believe.
