Actor Jesse Tyler Ferguson is calling on fans who don't share his support for gay marriage to unfriend him on Facebook.

The 37-year-old Ferguson, who is best know for playing Mitchell Pritchett on the ABC sitcom Modern Family, in September announced his engagement to boyfriend Justin Mikita, a lawyer.

Proceeds from sales of the couple's custom bow ties at Tie the Knot benefit organizations seeking to expand marriage rights for gay and lesbian couples.

In a Sunday post on his Facebook page, Ferguson expressed shock at the pushback he has received over his position on the issue.

“As an actor I have learned that I have to develop a thick skin but as a HUMAN I am having a harder time. The amount of vitriol I have received in the past few days over my stance on marriage equality could kill an adult horse! The majority of my fans have been amazing & supportive. But I am in shock and ashamed of many of my 'fans' who are standing firm in their stance that I am 'less than' them because of my sexual orientation. To those who feel this way: I gladly show you the door and wish you well on your journey,” Ferguson wrote.
