Schroeder made the remarks during a discussion about Harry Potter on Tuesday. The 33-year-old directly linked gay people to paedophiles, claiming that it was inappropriate for author JK Rowling to make the character Dumbledore, Harry Potter's headmaster, gay.
"He's in school with little kids! You don't want to make that guy gay!" said Schroeder.
"I don't think it's the right thing to have a kids' book, and to have the headmaster that's locked away in this magical land, to be gay. That isn't the right kind of writing to do."
When he was challenged by houseguest Kalia Booker, who has a gay sister, he responded: "Don't start with that f**king s**t! Don't tell me the right answer for f**king TV!
"I don't give a f**k if your little sister is gay!"
CBS insisted that Schroeder's comments were not representative of anyone at the network.
"Big Brother is a reality show about watching a group of people who have no privacy 24/7 - and seeing every moment of their lives," the network said in a statement.
"At times, the houseguests make comments, reveal prejudices and other beliefs that we do not condone.
"Any views or opinions expressed in personal commentary by a houseguest appearing on Big Brother, either on any live feed from the house or the broadcast, are those of the individual(s) speaking and do not represent the views or opinions of CBS or the producers of the programme."
