transparently unthinking nationalism

Assume there wasn't anything Vladimir_M said that a believer in unthinking nationalism wouldn't have said. Such a person would rationalize the belief that according to some objective moral metric, one's own English nation is superior, other nations are different from England and each other but overall even the best of them are not as good, and vassal races such as the Irish are most inferior of all.

If enough Englishmen believe that, it becomes true that one can deduce from the English assassinating foreign politicians that they would assassinate Irish ones, but not from their assassination of Irish politicians that they would assassinate foreign ones.

The belief Vladimir_M advocated greatly resembles the raw nationalist one, but could instead be interpreted as a second order belief about what military types of a country, people generally holding such right-wing beliefs, would be more and less likely to do. That's how I interpreted it.
