"I'm sure other people in the business have considered reasons why they're doing what they're doing, but I do think that if you're gay you have a responsibility to come out"

Rachel Maddow is suggesting that if somebody is gay, they ought to come out and be open about it. She thinks that it is a duty to do so, and that it is very important for people to be truthful about their sexuality. She also indicates that other people in business might have their own reasons for not coming out, but that it is still important to be open and honest. Maddow is encouraging individuals to be happy with who they are and to not be afraid to be open about their sexuality. She thinks that it is necessary to be real to oneself and to not be ashamed of who you are. Coming out can be a tough process, but it is an essential step in being real to oneself and in being accepted by society.
