"Foreigners will run away if you say "We" in the first 15 minutes. When you introduce Korean history, you shouldn't emphasize "We" . Korean foods, Korean houses, Korean language, all are great but if you propagandize them as "One of a kind" that sounds like nationalism. Koreans need to recognize Korean culture is as unique as other cultures rather than "Korea is the best"."
He criticizes "Korean nationalism is the problem" "'5000 years of history' is fantastic word but you need to prove it scientifically. If you boast such a thing in outside of Korea, you will be a complete fool . It is better to show realistic history to foreigners in a structured manner instead of overdramatizing."
Here's one of the complete fools.
