Wow, I can't believe I forgot to mention this one.

Another bit of fanon that I see all over the damn place is that Rodney is a male chauvinist, or behaves like one even if he doesn't actually believe it, i.e. implying or outright stating to female coworkers/underlings/marines that they'd do their jobs better if they didn't have ovaries. This is especially annoying in genderswap fic.

I'd like to know where this idea comes from. He has no problem whatsoever with Elizabeth as leader, or Teyla as diplomat, trader and warrior. He has singled out female scientists for accolade when they were particularly brilliant or efficient ("the lovely and talented [and doomed] Dumais" in Hot Zone, frex).

( Really, this one merits exploring )
