Prop 8: 'Modern Family's' Jesse Tyler Ferguson weighs in A picture is worth a thousand words. But for this photo Jesse Tyler Ferguson of "Modern Family" spelled out 11 of them after a federal appeals court Tuesday declared California's ban on gay marriage under Proposition 8 unconstitutional. Ferguson, who is gay and plays a gay character, Mitchell, on the ABC sitcom, sent out the picture above in a Twitter blast, saying: "Mitch & Cam have a question for you. @AFER #prop8 #MarriageEquality." He followed it up with a series of tweets that voiced his opposition to the controversial proposition.
