This is most screwed up:

Japan's burakumin (ぶらくみん, 部落民) - Japanese in Japan - are still by and large outcasts because they used to do things Buddhists don't like:

How far have they come since Japan began carrying out affirmative action policies for the buraku four decades ago, mirroring the American civil rights movement? If the United States, the yardstick for Japan, could elect a black president, could there be a buraku prime minister here?

The questions were not raised in the society at large, however. The topic of the buraku remains Japan’s biggest taboo, rarely entering private conversations and virtually ignored by the media.

The buraku — ethnically indistinguishable from other Japanese — are descendants of Japanese who, according to Buddhist beliefs, performed tasks considered unclean. Slaughterers, undertakers, executioners and town guards, they were called eta, which means defiled mass, or hinin, nonhuman. Forced to wear telltale clothing, they were segregated into their own neighborhoods.

The oldest buraku neighborhoods are believed to be here in Kyoto, the ancient capital, and date back a millennium. That those neighborhoods survive to this day and that the outcasts’ descendants are still subject to prejudice speak to Japan’s obsession with its past and its inability to overcome it.

Yet nearly identical groups of outcasts remain in a few other places in Asia, like Tibet and Nepal, with the same Buddhist background; they have disappeared only in South Korea, not because prejudice vanished, but because decades of colonialism, war and division made it impossible to identify the outcasts there.

In Japan, every person has a family register that is kept in local town halls and that, with some extrapolation, reveals ancestral birthplaces. Families and companies widely checked birthplaces to ferret out buraku among potential hires or marriage partners until a generation ago. The practice has greatly declined, though, especially among the young.

The buraku were officially liberated in 1871, just a few years after the 13th Amendment abolished slavery in the United States. But as the buraku’s living standards and education levels remained far below national averages, the Japanese government, under pressure from buraku liberation groups, passed a special law to improve conditions for the buraku in 1969. By the time the law expired in 2002, Japan had reportedly spent about $175 billion on affirmative action programs for the buraku.

I don't give a damn if being a vegetarian is morally superior to meat eating, and I certainly believe that's the case for the death penalty versus the alternative, but the idea to penalize descendants of those who did such things, especially when those who did such things were part of the overall social contract is repugnant.

And that this was/is done in the name of Buddhism is quite repugnant as well.
