Mark Twain victim blaming Christian Missionaries in Boxer Rebellion

PBS Ken Burns documentary quotes Mark Twain as blaming US Christian missionaries for the Boxer Rebellion in China. This seems insane. From a secular humanist POV, Christian missionaries were one of the few organizations providing any kind of social services or schooling to the general population and the thanks they received was lynching and murder.

Additionally, attempting to smear US involvement in putting down Boxer Rebellion as an example of imperialism is complete malarkey:

China paid reparations for destruction of foreign property to all countries attacked by rebels and the US was the only country to reinvest money back into China by establishing Tsinghua University with the funds:

Located in the northwestern suburbs of Beijing, Tsinghua University was established in 1911 on the site of “Qing Hua Yuan (Tsinghua Garden)” —a former royal garden of the Qing Dynasty. Partly funded by the “Gengzi Indemnity”, also known as “Boxer Indemnity,” it functioned at first as a preparatory school called “Tsinghua Xuetang (Tsing Hua Imperial College)” for those students who were sent by the government to study in the United States.

I agree with TommygunNG6:

 "You call it, 'imperialist'  I call it the march of our civilization."
