When will man = woman? Will it ever happen?

I think people need to keep having the discussion to figure out where the "line" is -- it's a constantly shifting one, and has varied over time with things like voting rights, labor rights, etc. And because the species is always evolving, I'd expect the line to continue to evolve based on where humans are. No, there's never going to be some fixed agreement forever and ever, just like there aren't going to be fixed laws forever and ever and then the entire government packs up and goes home forever.
