In my humble little stuffed opinion, Aunt May discovering and dealing with the revelation that her nephew is Spider-Man was one of the greatest growth stories and potential spin-off for dozen upon dozens of fresh storylines. (So of course, they retconned it away.)
The comics you are about to see are products of their time. They may depict some of the ethnic and racial prejudices that were commonplace in American society. These depictions were wrong then and are wrong today. While the following does not represent the comics industry view of today's society, these panels are being presented as they were originally created, because to do otherwise would be the same as claiming these prejudices never existed.
