@Tfmonkey To answer your question why no nazi has ever created a virus that kills all black people, the answer is simple. Its because I don't think there is a single nazi that exists that has the money and virology education required to actually do it. Also the technology does exist its just unreliable. Its like wind turbines. Sometimes they work, most of the time they don't. Also, sometimes they mutate and start killing indiscriminately again. Bioweapons are taboo for a lot of good reasons.
