Something that's thrown me out of a few scifi stories lately (mostly written pre-1980s, but some very very recent) is gender roles. I think it's bizarre to read about a future-Earth that has changed extremely in governing structures, technology, economy, ethics, etc etc etc, but all the women have no function in life that is not tied to sex with men, reproduction, or taking care of men.

It's not like I can't conceive of a future in which is the case, but I damn well want an explanation.
