2,500 years ago, members of one Greek city-state considered members of another Greek city-state subhuman and treated them that way. And then this moral revolution arrived, and they decided that actually, no, Greeks are human beings.
Acum 2500 de ani, membrii unei cetati grecesti ii considerau pe membrii unei alte cetati grecesti ca fiind sub-umani si ii tratau ca atare. Si apoi a aparut revolutia morala, si s-a decis ca, de fapt, grecii sunt fiinte umane.
