It’s a nice analogy, but the problem with it is that womanhood does not have a government, with an immigration and naturalization service. The government has a right to do a lot of things that individual citizens do not have a right to do. Among others, it gets to decide who has a right to live here and who doesn’t. No individual, or group of individuals, has a legal right to say to a Somalian-born person with US citizenship “you’re not a citizen! You have no right to be here!“ The question is, are TERFs the immigration police, or are they a lynch mob?
