Well, the greeks did very well didn't they? Lol. Homosexuality is a weakness not a strength. Even the greeks were aware of this. It wasn't thought of as a 'good' by philosophers of that time, socrates for example. He taught against mere lust.

This about how the world would view a homosexual nation. Think about the state in which our army would be in, if it had a predominant homosexual population.
