That is not what the parable of the Samaritan was implying, nor the context of it. Samaritans were and are an ethnic group that historically has had friction with other Semitic groups (notably, Jews). They were not in any way "Nazis of their day," and the parable was not about that particular Samaritan being better than other Samaritans, but about morality being a stronger tie than culture.
