(..well maybe not so much censored as rejected by editors/"No can do")

Know any examples? Here's some Ive seen or heard about :

Nude Batgirl change scene in Batman adventures special

Jesus as a character in Swamp thing (post Alan Moore period)

Elseworlds 80 page giant

Preacher - sex detectives one-shot

Greg Rucka gave a talk at a con about a rejected Batman story he had. It featured a bunch of women Bruce dated telling stories about how he ducked out on dates with all of them. The girls suddenly come to a conclusion. Bruce is..... gay! The ladies feel sorry for him being alonein that big "closet" of a mansion and vow to protect his "secret life"....

Others?
