"Star Trek" actor Zachary Quinto's coming out as gay via a profile in New York magazine made a lot of noise this weekend.
Even in 2011, with the repeal of "don't ask, don't tell" and gay marriage legal in New York, an A-list actor's decision to leave the closet isn't one made hastily or without losing some sleep.
The fear of being shunned by casting directors concerned about a gay actor's ability to convincingly play straight and worries that he or she will end up alienating a major portion of his or her fan base has kept and continues to keep many in Hollywood closeted.
Still, we've come a long way over the past 25 years and as more and more stars make the choice to come out, the LGBT "community" gains new role models, especially important for isolated youth, and greater visibility overall which helps alter, shape, and define the way mainstream society understands and views what it means to be LGBT.
