You sound as if you look forward to its return? All forms of slavery are evil because slavery stands on the assumption that one person is less than another or that if one person finds themselves indebted to another slavery is a natural and righteous alternative. This is evil thinking. There is not benevolent slavery or caste. It is all about, we have it, we want more, and we do not mind using whomever to achieve our goals. I am for defeating the ideology of slavery, and disenfranchising those who promote it.
