Yeah but they didn't have the same sense of identity. Stan Lee was, typical to many young men of his community at the time, was assimilationist, who believed that "Americanism" i.e. the US constitution, patriotism, land of opportunity and all that, was enough of a susbstitute and alternative to religion which was typical of early mid-20thC secular Jewish identity.
Jack Kirby was more religious and religiously observant, though he was also somewhat idiosyncratic as well and not someone you can pin down to any single school of Judaism.
A lot of writers and artists of the early comics days were Jewish but they were also individuals with their own ideas, thoughts, experiences, and philosophies. They were not a monolith. Likewise, they didn't have a uniform attitude to comics. Not all of them thought that commercial work for newspapers, monthlies, children's comics and so on would lead them to think "this is a medium in which I can express my personal beliefs and identity".
Will Eisner, also Jewish, and largely secular, felt far more comfortable exploring those issues in his graphic novels like "A Contract with God" than he ever did when he worked on "The Spirit".
Ultimately for Peter, his Uncle Ben and Aunt May mean more to him than any organized religion.
So the question is moot.
