I know that I have written about this previously but this is a topic that really interests me. About two months ago in a issue of Ms. Marvel an honest to goodness Orthodox Jew was introduced as a supporting character in the book. What's more interesting is that the character is treated with respect and his beliefs are respected.
Another interesting aspect of this introduction is the writer of the book G. Willow Wilson took the time to be interviewed by Tablet Magazine and she shows an amazing amount of sensitivity to the subject. I'm now a fan of her work just because how thoughtful and sensitive she is to these kinds of things.
