Regalado saw the character as pushing the boundaries of acceptance in America. The extraterrestrial origin was seen by Regalado as challenging the notion that Anglo-Saxon ancestry was the source of all might. Gary Engle saw the "myth of Superman [asserting] with total confidence and a childlike innocence the value of the immigrant in American culture". He argues that Superman allowed the superhero genre to take over from the Western as the expression of immigrant sensibilities. Through the use of a dual identity, Superman allowed immigrants to identify with both of their cultures. Clark Kent represents the assimilated individual, allowing Superman to express the immigrants' cultural heritage for the greater good. David Jenemann has offered a contrasting view. He argues that Superman's early stories portray a threat: "the possibility that the exile would overwhelm the country". David Rooney, a theater critic for The New York Times, in his evaluation of the play Year Zero considers Superman to be the "quintessential immigrant story [...] [b]orn on an alien planet, he grows stronger on Earth, but maintains a secret identity tied to a homeland that continues to exert a powerful hold on him even as his every contact with those origins does him harm". Religious themes Some believe that Superman took inspiration from Judaic mythology. The British rabbi Simcha Weinstein notes that Superman's story has some parallels to that of Moses. For example, Moses as a baby was sent away by his parents in a reed basket to escape death and adopted by a foreign culture. Weinstein also posits that Superman's Kryptonian name, "Kal-El", resembles the Hebrew words קוֹל-אֵל (qōl ʾēl) which can be taken to mean "voice of God". The historian Larry Tye suggests that this "Voice of God" is an allusion to Moses' role as a prophet. The suffix "el", meaning "god", is also found in the name of angels (e.g. Gabriel, Ariel), who are airborne humanoid agents of good with superhuman powers. The Nazis also thought Superman was a Jew and in 1940 Joseph Goebbels publicly denounced Superman and his creator Jerry Siegel. All that said, historians such as Martin Lund and Les Daniels argue that the evidence for Judaic influence in Siegel's stories is merely circumstantial. Jerry Siegel and Joe Shuster were not practicing Jews and never acknowledged the influence of Judaism in any memoir or interview..
