David Koch on Shen Yun and Giving to New York American Ballet Theater

So in a recent video interview with NTDTV David Koch called the work of Shen Yun "inspirational and put him in a good mood". David Koch donated $100 million to the New York State Theater (which they renamed after him). David Koch has been attending the theater for 45 years (he is now 72). Koch has always said he loves the athleticism of the ballerinas, good music, and attractive women. Speaking of women David Koch was quoted saying "When you have spent as many years as I did begging girls for favors you'd have bad knees too". David Koch has had his knees artificially replaced, his prostate removed, in addition to having 10 surgeries at the New York Hospital of Special Surgery (he also donated $25 million to them). 

Speaking of dancing the only dancing David Koch did was at discotheques according to this Bloomberg story. Koch for years was giving $500,000 to the New York American Ballet Theater. He was so generous he gave $2.5 million for the Nutcracker production. Even Koch's daughter was taking lessons at the School of American Ballet in New York.

I am not really sure why so many people think David Koch is such a bad person. He is a prostate cancer survivor, father, generous donor to the arts, sciences, and cancer research. Although, people may disagree with his policies does David Koch really seem that evil?
