This happened at "Sweet Cakes by Melissa" in Gresham, Oregon, a conservative, low-income suburb of Portland. Notice that even though the owner cites Biblical scripture against same-sex marriage, he has a visible tattoo and piercing (Leviticus 19:28).
UPDATE: Sweet Cakes by Melissa posted a racist rant on their official facebook page before shortly deleting it: "F**k the N**gers, Sp*cs, whores, sodimites (sic), fat b**ches, ugly c**ts, hypocritical hoes and overweight hippos on our feed."
Update II: A newly revealed screen shot of Aaron Klein's facebook page shows him saying this about Obama, "Send him back to his socialist utopian gay rights loving homeland. And all the people that think like him can go too." To all the defenders of this bakery saying his facebook was hacked, what do you have to say now?
