You seem to have a large (and valid) sample of right-wing exhibits in the Museum of Affirmative Action, in the spirit of the 3 thirds, please allow me to suggest a few additions to your collection that you may have overlooked:
Josef Stalin and his 1930's purges (10-40 million through state-ordered famine, executions, and deportation to labour camps)
Mao-Tse-Tung and his Cultural Revolution (Destruction of all public paintings, sculptures, theatres, literature, houses of worship, and universities)
Pol Pot and the Killing Fields of Cambodia (2 million, plus the outlawing of ALL art, education, religion, and family structure).
Frighteningly enough, there seems to be no end to the potential subjects for exhibit in this museum in the annals of history. No matter how large a hall you build, mankind seems capable of creating more than an adequate number of individuals worthy of inclusion in this dubious club.
