Hitler and his Nazi regime killed killed nearer 25 Million according to the best historical estimates, just for the record. As for his home I don't care that they are to destroy his birthplace! Actually I thought they had actually destroyed it long ago!
Perversly the birthplaces of the other infamous butchers of humanity whose crimes are still just within living memory, Lenin, Stalin and Mao, still exist and are open for business!
Lenin's childhood home is in Simbirsk, the Joseph Stalin Museum is in Gori and Mao Zedong's is located in Shaoshan Village Shaoshan City. The best estimates for deaths in the USSR are circa 60 Million and 32 million for Mau.
