If I may share some thoughts on this matter...
I think racism can be found in most, if not all countries, in the world...
And I've observed this at least in the ones that I was able to visit so far, both on short & long term bases...
Probably, it's just part of our fallen nature as humans to "complain" about many things, particularly on appearances...and even body odour.. That's probably why we invented perfumes... Haha!
But on a closer analysis, the good in people still outweigh the bad...
Many folks in many countries are generally friendly...they greet strangers randomly...like it's a habit...lol.
I remember being "hugged" suddenly by a bunch of gorgeous African women, after a public presentation in Freiburg...I felt thrilled and lost my speech for a moment...Haha!
In SK, most people don't randomly & openly greet everyone, esp foreigners... But they are "stoically polite" I should say...
They got lots of coffeeshops & noraebang (videoke bars) there and really love to socialize...(with chicken & beer) which means getting drunk and wasted afterwards...just like how there are lots of pubs in London & how Brits love to drink (with fish & chips) and get wasted as well...it's all for fun! Lol.
Just like Hollywood, K'ent in SK does not really permeate the lives of the citizenry or the regular folks...most are busy working, studying, or scrolling their smartphones...
