Howard Bragman, the founder of Fifteen Minutes, a Hollywood public relations company, is a well-known publicist who says he has "brought more people out of the closet than anyone else." He agreed with Barrios that coming out in Hollywood is getting easier.
"Every person that comes out makes it better for others," Bragman told ABCNews.com. "But it is still definitely not easy."
Bragman said that it would be hard to prove that coming out prevents actors from getting cast in certain roles, but that he is "sure there is still homophobia in Hollywood."
"In the end, it is called acting for a reason," Bragman said. "You need only look to people like Neil Patrick Harris and T.R. Knight to see that gay people are playing straight and doing it well."
"The single biggest thing anybody can do to help gay rights is to come out of the closet," Bragman said. "And I think every new star that comes out is helping to show that the sky doesn't fall in when someone comes out of the closet. In fact, most of the time that star lives a happier life and is still respected in their field."
Barrios said that Martin's coming out is a "game changer for gay folks and for Latinos."
"Ricky is a celebrity in English language culture," Barrios said, "but in Spanish language cultures he is a super-celebrity."
"The impact on women that were fans of Ricky when he was in Menudo is going to be profound," Barrios said. "They might have children coming out to them and they aren't going to see gay people as some sort of stereotype. They will see them as Ricky Martin, this person they know and love."
Bragman said Martin's move would start a conversation in the Latino community.
"The Latino community has had issues with homosexuality in the past, and Ricky coming out will definitely start a dialogue within the community," Bragman said. "Also, he is living in Florida, a state that doesn't allow gay parents to adopt, and he is obviously a gay parent. Hopefully that will start another dialogue on that subject."
Here are some other celebrities who recently came out:
Fans must have been surprised when the matriarch of the Keaton family on "Family Ties" announced that she was a lesbian.
Last December, Meredith Baxter sat down with Matt Lauer on the "Today" show to tell the world she was gay. Baxter, who has been married three times and has five children, said that her attraction to women "was a later in life recognition of that fact."
"It has only been for the past seven years," Baxter told Lauer. "I got involved with someone that I never expected to get involved with and it was that kind of awakening."
By the time Baxter came out on "Today," she said she had been in a serious relationship for four years with Nancy Locke, an L.A.-based general contractor.
Bragman helped Baxter with her announcement.
"We knew the tabloids had the story because Meredith had been seen on a lesbian cruise, and we decided that we wanted to say something before they could," Bragman said. "I helped Baxter understand what to expect as opposed to what to say. I helped her on how to say what was authentic to her, rather than put words in her mouth."
Barrios said that Baxter's coming out forced people to question their stereotypes and "reconsider who a lesbian is."
"When a celebrity who is a mom and who is liked comes out," Barrios said, "It challenges people's truth and they become open to a new opinion."
