I think FD are using the only thing they can with this story arc, current human reactions to a crisis. As Col568 said, for the vast majority of humanity, if something isn't effecting you directly and personally, whilst you might take some vague interest in it, you know it won't impact your day to day life, it is just background static to you. Loot at the reaction the Thargoids have on just this community, some immediately jumped into the CG's so they could get the necessary weapons, outfitted the ships and went hunting these strange craft. Others started threads saying why are we even attacking them, why can't we extend the olive branch of peace and all live happily ever after. And a lot went 'meh' they aren't near the area, Thargoids aren't effecting them, they just go about doing business as usual. Exactly the way humanity is now, so why should things be different in the 34th Century?
Precisely. On a large scale, people are acting exactly the way they do now.
