Now on a serious note, I enjoyed the plot twist with the expedition/starghosts in Aftershock, and I have a generally good opinion on the Reticulan Expedition.
But everyone around is talking about fighting them.

Is this the wargamer in you, wanting to see the glove a big swath of blue?
Or do you simply despise anything Reticulan (Grey or Sectoid, if I may) to the point of "Shoot on sight"?

Or is there a particular reason to kill those guys? Not sure if I wanna, seeing as Preggie makes Martians cry.
