[Star Trek] Was Noonien Soong's given name ever described as taboo? After the Eugenics Wars, it kind of feels like naming your kid "Adolf".

Modern Trek really overhypes Khan as the definitive Big Bad of Earth's past, but that's not really the case. When Kirk's crew first picks up Khan and popsicles, they don't even recognize him. They have to look his name up in a database just to see who he is, so that answers your first question. The name "Khan Noonien Singh" to the modern Federation would be like introducing yourself as Temujin at your local gas station. Sure, a history buff might perk up a little bit at the name, but the everyday person would still need to wiki search you to find out who you were.

Even when the crew learns Khan's true identity, they actually kind of love him. It's not an instantaneous negative reaction like if you were to meet Hitler, they actually hold an honest debate between them if Khan represents the classical idea of the benevolent tyrant. Only Spock remains somewhat skeptical, and even then, the crew of the Enterprise only turns on Khan when he holds them all hostage. 

So maybe in the immediate aftermath of the Eugenics Wars, the name Khan Noonien Singh would have held some stigma, but that entire period of history seems to hold more of a stigma towards the practice of genetic manipulation and enhancement than towards any one individual person.
