Recently I read on TV Tropes that Chuck Dixon picture the New Earth Tim Drake as jewish when writing the character. This was a little under 2 decades before Drake was confirmed as an atheist during Red Robin. I just found the fact interesting.
Chuck Dixon is one of those writers who imagines characters a certain religion when writing their character, even when it doesn't reflect on the page, or ever gets mentioned, or is necessarily true. It helps him build the characters, maybe?
