alt Hacker NewsThis is an oversimplified strawman argument. Biological sex is a complex subject. The cultural understanding of sex is complex. If I has a man take my 2 year old daughter to the men's room is that a bad thing? (For the record I don't have any children)
I don't think anyone is arguing that you should be barred from taking your hypothetical two-year-old daughter into the men's bathroom if the need arises. That's really not the issue.
