Which political party is the worst?

[DC Al Fine]

The Republican Party is pretty much on par with some of the worst offenders of human rights in human history, given the sort of things its members and leaders have engaged in over the years, which include, but are not limited to:

Genocide of Native Americans, engaging in naked imperialist wars abroad (Cuba, The Philippines, the various 'Banana Wars' of the late 19th and early 20th Century, Vietnam, Cambodia, Laos, Iraq), acting to imprison or murder political dissidents (the Black Panthers), criminal denial of basic human needs in favor of spending more money on armaments, etc.

Perhaps only the Democratic Party is worse, in terms of a major national political party in existence today, given its record of promoting and consolidating the institution of slavery in the United States.

CCP? Worker's Party of Korea? Also as Sol says, by this reasoning the Tories can be blamed for the evils of the British Empire.

Khmer Rouge? etc. etc.
