If you're not sheeple, you would understand that men, in whatever civilization or whatever culture aside from pacifistic ones, usually seek out more space and places to expand their civilizations towards.

Ask your fellow menfolk that have a say-so to stop being hellbent on power, land and wealth. I'm sure they'll totally listen.
