>false rape accusations against men
this is actually a serious problem not just for republic of samsung, but for my country as well, and maybe even in your country. be careful

>Please elaborate.
their culture is somewhere between japanese idols and famine torn past. all they know is to destroy the ones beneath them (socially and economically), they are extremely xenophobic to the point that you MUST NOT immigrate there (or else you die socially, economically, psychologically, or literally), and other stuff that i am unfortunately not really educated in.
thier women are a joke, along with their males. the whole gender war thing. the gender ideology disparity. if robot sex is gonna emerge, it will probably emerge in south korea first.
their academia is a total joke as well. they think they are doing research, they are being scientific, being democratic, being open minded.. but no. they are just abusing employees, assistants, and doing no job themselves. they sometimes even extort the people beneath them for academic success.
i don't think i need to explain the fertility rate. and their neighbours. BEST KOREA will someday annex them and southerners will not be able to do anything about it.
lastly, it is extremely urbanized, and half of the country is in one city. its like a total dystopia.

>bizarre religious movements getting big
I remember back in mid 2010's there was a korean restaurant in istanbul selling weird sushi things, korean sweets and chicken noodles. around late 2010's someone on twitter made a flood about how that particular korean restaurant was tied to some korean radical religious group both monetarily and ideologically, their owner was the member of the said cult, and even called them a terrorist organization, etc... the restaurant doubled down and made a statement: "that religious group is not a terrorist organization. it is a religious group and is benevolent." lol
and here's the link to that cult thing: https://www.koreatimes.co.kr/www/culture/2019/02/293_263104.html
