I've read in multiple places that 4B is just an online thing, maybe a couple of thousand women, that has blown up in western news media and not a real life thing in Korea.
you are correct. Western news media wants it to be bigger than it is right now, because if you check the last month or so, the only people ever talking about 4B movement are western liberals and hmm i wonder why Western Media outlets are obsessed with talking about 4B since trump became into power. Dubious motives.
