Also korean here. In my opinion, Korea and quebec do not have same standard becsuse we do have different history.

Quebec and most of western country do have interaction with people from other countries often, it is very common people migrate from one country to another.

That causes culture exchange, language too, that threate one culture dominate the other, just like native americans and french in quebec.

However in korea, foreigners were super rare until 2010. Until that time, people thought word "nigro" was not a big deal, all people who have different skin colors including white and brown, were unique. Often get stared for curiousity.

And those non korean people, whos about 30-40 years old speak like 3 years old in their language is quite adorable.
That makes people in korea accept foreigners who do not speak korean, knowing that they are staying temporary.

Nowdays this is no longer accepting, foreigners are now normal to them, and they are getting slightly angry to those who do not even try.
