What would happen if LW had a similar "soft taboo" about e.g. religion?
There is a rather large difference between LW attitudes to religion and to gender issues.
On religion, nearly everyone here agrees about religion: all religions are factually wrong, and fundamentally so. There are a few exceptions but not enough to make a controversy.
On gender, there is a visible lack of any such consensus. Those with a settled view on the matter may think that their view should be the consensus, but the fact is, it isn't.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
