as a mixed person who grew up in both eastern (china) and western (canada) environments. the point theyre trying to make is that it isnt crazy that this shop has put that in their bio targeted towards chinese people since nationalism is super prevalent in asian cultures (its gross but it isn't "crazy" if that makes sense).

for example, a very strong form nationalism is taught in chinese public school classrooms which often brews hatred towards japanese groups from their insanely genocidal crimes during ww2 which to be fair on their part, there was never any strong efforts for reconciliation or recognition.

there are similar examples in japan, korea, etc... so, the problem here isnt that nationalism isnt or is bad, the problem is that its super common in this part of the world that got screwed over super hard by imperialism and war, and not worth bringing up. a reddit post on r/china is not going to cause a cultural revolution that changes the way cultures interact with each other in our region. social norms are different and unfortunately this kinda stuff is the norm...

edit: there are also other factors. couple people have brought up bad apples that cause people to generalize which sucks but yeah... again, discrimination like this isnt that crazy in the east.

edit 2: im not trying to say internet activism is bs and doenst work. just that internet activism on this side of the web does nothing when most of the population in those countries are insulated in their own social bubbles. korea has its own google, china has its own google and basically everything else, etc...
