This is likely one of the most pointless exchanges on this forum and fool that I am, I've been furthering it. I've enjoyed it though, so I'll leave you with a final thought, and then let you have the last word:
Your assumption that aliens, advanced enough to travel to Earth would obviously be far wiser and more benevolent than we stems from the same self-hatred that makes Americans travel to foreign countries and apologize for being Americans.
But the solution is simple: When the aliens land, volunteer to drive the welcome wagon to meet and greet them. When the rest of us see what happens to you, for the good or for the bad, we'll be prepared for a more informed approach.
