Misled self claimed patriots exist in any country. They are often classified 

as ultra conservative right wing. During the end of Chosen dynasty, 위정척사파

is an example. Confucianism is the right thing. Foreign influence is the wrong thing.

It is a common sense to keep the right thing and discard the wrong thing. 
Unfortunately the public was misled to believe that Confucianism is the right thing 

and the foreign influence is wrong thing by corrupted establishment, i.e. 양반.
