Except that in your proposal, the aliens decide to eradicate Earth for more "breathing room", not because it's either their society or ours.Lord of the Abyss wrote:Your attitude is the sort held by people who never expect to be on the wrong end of it. If some aliens showed up and started slaughtering humanity, and explained their action by saying "great, more breathing room!" and "when it comes down to My Species expanding out and thriving onto other worlds, other species are Shit Out of Luck.", I doubt you'd appreciate the turnabout.
I didn't read a line where Solauren advocated eradicating alien species for the sake of more breathing room, he simply said that, as per the OP, if he was faced with a choice between sacrificing humanity and the rest of the galaxy, he'd choose the rest of the galaxy.
Admittedly, the idea of losing ump-teem number of sentient individuals for the sake of our own species seems horrifying, but there's a part of me that would rather see our own kind survive, despite the numbers.
It would be a very hard decision to make if I was faced with it, but right now, since I'm under no pressure, I haven't decided yet.
