The 4B movement predominantly sees transgender rights movements as incompatible with feminism.[10] Developing out of transgender-exclusionary radical feminism (T.E.R.F.), the movement holds to gender-critical views on sex and gender,[10] supporting gender essentialism and the exclusion of transgender women from feminist spaces.[12][14] Advocates of 4B are opposed to what they call “gender ideology” (젠더론x) and promote excluding transgender women from feminist spaces, as well as romantic or sexual relationships with them (트젠 안사요).[10] In South Korea, members of the 4B have created gatherings exclusively for what they call “biological females” and “real women”.[10]
yikes
The American version need not be TERF though. It is not an inherent part of what 4B actually entails and is extraneous to the purpose of 4B.
