Because, as S.A.T.A has pointed out, different people have different concepts of good and evil. Human sacrifice may seem evil and barbaric to you and me, but it was not to many other people in the world. In fact, it was considered an honor to be sacrificed. No one in the Aztec or Mayan civilizations viewed it as "evil", but the Spanish did, and they used their prejudiced view of Mayan culture as a justification for genocide and mass (forced) conversion.
We should not make the same mistake, in the modern era, of being close-minded in our view of other cultures. We have no right to force our judgement of "right" and "wrong" on other people.
That doesn't address my point.
You were comparing unlike things, so you didn't have a point in the first place.
Human sacrifice is an ordained ritual in many Mesoamerican religions, just as praying five times a day is an ordained ritual in Islam. You cannot change this.
However, killing people in the name of Jihad is not an ordained part of Islam, nor is totalitarianism and the use of secret police an ordained part of Communism. No where in any Islamic or Communist text does it justify this. In fact, both movements preached the exact opposite when they began. Both jihadism and Stalinist totalitarianism can thus be labelled as "extremist" because they diverged from their original movements to become rather different and incongruent things.
Human sacrifice, on the other hand, cannot be labelled as "extremist" because it part of the mainstream religion of Mesoamericans. That is the difference.
The people; yes. The system itself; no.
And that is why democracy, in itself, is not the answer. In order for democracy to succeed, other things need to be present, such as a strong legal system, a well-established system of education, and a relative degree of socioeconomic equality. Without things like these a democracy is doomed to fail.
Unless it explicitly states within the political system (democracy for example) to enslave or treat people in an unequal manner, then no that political system is not responsible for the actions of the people under it.
The U.S. Government passed laws that specifically targetted minorities throughout its history. These laws were passed through the "democratic process".
Indentured servants' seems to be a euphemism, what about those who were on the bottom end of the caste system who were basically treated as slaves?
Slaves are not paid, protected under the law, or guaranteed their freedom after a certain period of time. Indentured servants are, and that is the difference.
The concept of "human property" is a foreign concept in India. You will find no such reference of 'slaves' in Indian literature. Even the labourers on the bottom end of the caste system were guaranteed their right to freedom and were protected by law. It is ironic that people criticize the caste system when it was probably the freest system of ancient times; India was one of the few societies where outright slavery did not exist. It was only until much later that the caste system became oppressive and limited social progress.
I have read this text, and nowhere does it abolish the notion of slavery
Why do you need to abolish something that doesn't exist? The concept of "abolition" requires the concept of "slavery".
but that does not mean they weren't enslaved when the Mauryans or other Indian kingdoms captured foreign territory.
There were only two instances in history when an Indian state captured foreign territory. The first was in the 4th century B.C.E, when the Mauryans conquered present-day Afghanistan from the Seleucid Greeks. The second was in the 11th century C.E., when the Chola Empire conquered Indonesia and Malaysia. In both cases, there is no evidence that Indian rulers enslaved the peoples of those regions.
In fact, there are Greek sources that specifically state that slavery was not practiced by the Indians, which I have already posted.
There seems to be a double-standard for what Europeans did in the past, but a white-wash of what others have done.
There is a reason why this is.
No other people in the history of the world depopulated an entire hemisphere, and then enslaved countless millions of people from another continent in the other hemisphere and sent them over to the depopulated hemisphere. It was a demographic shift of unprecendented proportions, and unprecedented suffering. That is why the Europeans are blamed more than anyone else, which they deserve to be.
