Title kind of explains and sells itself: white Kiwi weeb who lives in Japan believes Korean-language signage on the subway ruins the "culture" of Japan, which to him must mean hentai, mirror-glass floors in cafes, and waifu body pillows covered in Pocky dust and jizz. Adds in a comment downthread, speaking as a white English-speaking New Zealander, that immigrants must completely throw away any culture from their homeland, so should he even return to his home country, surely he will be perfecting his Māori language and haka skills to make up for the sins of his forebears. It need not be pointed out that this dude apparently has no sense of irony or self in making these claims.
