Che Guevara glorified the idea of nuclear war against civilians. He said:

“If the nuclear missiles had remained [in Cuba], we would have used them against the very heart of America, including New York City…We will march the path of victory even if it costs millions of atomic victims…We must keep our hatred alive and fan it to paroxysm.”

He was a racist, who said:

"The blacks, those magnificent examples of the African race who have maintained their racial purity thanks to their lack of an affinity with bathing, have seen their territory invaded by a new kind of slave: the Portuguese.” 

And also: 

“The black is indolent and a dreamer; spending his meager wage on frivolity or drink; the European has a tradition of work and saving."

He was a proud Maoist Communist, and said that there was "not a single discrepancy" between Mao's world view and his own. In China, Chairman Mao killed an estimated 40 million Chinese in his quest to implement his brand of Communism.

Finally, Che Guevara oversaw many executions (at least 500) of political prisoners in Cuba's La Cabaña Prison. 

Murder, genocide and political executions have no place in the American dialogue. America has not always been perfect, but it strives to be a place where divergent ideologies can discuss ways to improve the American society. Che Guevara, who advocated genocide, tyranny and murder, should not be glorified by products sold on Amazon.com.
