Gay groups are asking booksellers Amazon and Barnes & Noble to stop selling Christian cartoonist Joe King's I'm Not Gay, I'm Just A Sissy 2012 calendar, which includes the tagline, “12 Months of Sexual Confusion (Not that there's anything wrong with that!)”

After popular gay blog Towleroad.com brought attention to the calendar – which includes the caption “WE ALL HAVE AIDS! – King hit back in a Facebook post.

“Hoo-we! Hell hath no fury like a he/she scorned. … The telephone tree of tantrums is lit up like a Las Vegas marquee for ‘Boy-Lesque’ today with hate mail, threats of boycott and even the risk of Jesus spitting on me for my 'Sissy' calendar. I SAID I WAS A SISSY UP FRONT. Ironic who the real bullies are isn't it? Let’s see if I get a call from Oprah's people or even Anderson Cooper. ...”

And added: “The 'truth' is that AIDS is an 'elective' disease. It STOPS the day guys quit sticking it to each other. And for the tragedy of women and children infected … THAT stops the day their gay husbands and fathers stop cheating on them. Anyone need MORE education, science or funding to understand THAT?”

The Gay & Lesbian Alliance Against Defamation (GLAAD) called the product “dehumanizing” in calling on booksellers to dump the calendar.

“This calendar has no business being sold and supported by reputable retailers,” Herndon Graddick, senior director of programs and communications at GLAAD, said in a statement. “King has a right to his opinions, however anti-gay or anti-transgender they may be, but retailers also have the right to decide that they don't want to support hateful and dehumanizing content like this.”
