text: Seeding by extraterrestrials is about the only scenario justifying describing humans as 'invasive species'.
  
  I'm not minimizing hideous atrocities we humans perpetrate against our own kind when forcibly annexing territory and displacing its rightful occupants.  The Zionists' crimes against the original Arab and Berber inhabitants of Palestine, and feral Englishmen's crimes against this continent's, Australia's and damned near everywhere else's indigenous peoples are indefensible.  And in terms of survival such crimes against humanity aren't sustainable.
  
  Military 'superiority' and the economic largess derived therefrom doesn't automatically translate into cultural, ethical, moral or spiritual superiority.  It just means being superior at killing.  And that is ALWAYS a temporary situation.
  
  I will acknowledge it's possible ancient UFOs flushing their toilets in flight as modern commercial airliners do may account for some of the selfish, screaming idiots with whom we share this planet.
