One of the X-men books had a gay marriage on the cover recently. I wonder what my mother would of said if I got one those in the mail during the 90's. Both companies are just whoring themselves out for any bit of attention they can get. This was one of the reasons I stopped subscribing /collecting back in the early 00's.
difference being it was a marriage between characters that had been established as gay for years. sure it was an attention grab. but it was done within context. dc just decided to out a nikka randomly, with little consideration for previous history.
