Pinkalicious "The New Girl"

My daughter is four years old and loves to watch Pinkalicious. This morning she was watching "The New Girl" episode. A new family moves to town and its two men and a little girl. The man introduces his "husband" to Pinkalicious' family. I am so upset that this lifestyle was introduced to my preschooler with no parental warning or rating etc. I would not have let her watch the episode if I had of known that material was in there. It is not the job of APT or PBS to decide when my child gets introduced to homosexuality. And frankly in my opinion it should not be in preschoolers programming. They are very impressionable at this age and a certain agenda or lifestyle should not be made to seem okay thru a familiar children's program they love to watch. Something should be done about this! I see your organization helps fund the programming. Could there at least if nothing else parental warnings be put in place so parents wont be caught off guard that dont want their children watching episodes containing this subject matter? Thank you
