Following openly gay winger Robbie Rogers' return to MLS with the Galaxy, Keane suggests that he may have even played with some gay teammates during his time in the UK who were simply afraid of letting the general public aware of their sexual preference.
"I'm sure that there are a lot of players over the years that have played in England or wherever [who were gay] but are too frightened to come out ...," Keane said.
"I think it's maybe easier to cope with it in America than England, where they're maybe a little bit behind over there, in regards of the situation.
"I think maybe the fans are a bit more brutal than they would be here, but shouldn't be the case, because no matter who you are or what you are, everyone is the same. Everyone should be equal.
"It's 2013, for Chrissakes. People move on and to each their own."
