If you want to pretend everyone is nice move along.  No, truth be is that some people have real space lizard blood in their veins. Lizard people are all about hierarchy and being on top.  In BDSM terms they are on top.  Your are on the bottom.  Space lizard dominance.  Equity as a logical consequence of not being the only beings in the universe means nothing to them.  You mean nothing to them.

Because when you have global mobility you can leave a shitty place behind.
