Yeah, unconditional love = Extinction.
On a normal planet with ONE nation/people it could have worked, NOT on Earth, the most violent place in this galactic sector.

What I believe is that every single human should be trained how to use different weapons (blade-firearms) so that we can talk to each other as equals. Weak minds will defend themselves as "loving souls" and they go down easily.

Look at the Dalai Lama, he should be a brave buddhist but he doesn't dare to return back to Tibet, for example.

We should be heavily trained in Martial Arts before we could express great love.
