If you don't have anything to base an opinion on about another culture (other than some shit you heard), then don't express an opinion.
Spreading racist stereotypes about South Korean people is bigotry. This went well beyond criticism of the K-pop industry.
I bang on because it is a racist stereotype of Korean culture. It's a racist stereotype regardless of the source.
Quoting South Korean women is just a micro aggressive version of of the same racist statement.
Write and then deleted an essay on racism because I can't be fucked arguing with white people on offensive shit like this. Carry on.
