This 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.

but I thought "Being told that you have to follow the same rules as everyone else for e.g. spaces designated to be used solely by the opposite sex, doesn't seem so bad."?

[duckfan]

Perhaps think on that a bit more then. Consider for example that female-only spaces don't exclude women who are pregnant with male babies.
