What they won't tell you about the people outside home is that they'll cheer the loudest, they would never have to face a single danger or consequence from across the sea, but they will be the loudest advocates of violence.
As much as I am proud of who I am, I would not advocate for death against my neighbor for simple existence. That is not just how us humans should act, we are not mindless zombies that need to bring tragedy to the world.
