sf_swimmer saidNo, I think both choices still have their own challenges. Personally, I'm not one to conform to the herd mentality of "everyone's doing it," but I know a lot of guys want to fit in. I'm also repelled by the idea that I have to label myself for the general public. For me, the better approach is on an "as needed basis," like if I were seriously involved with someone. Otherwise, it's not really anyone else's business. Sorta like Sally Ride did.
There simply is no right or wrong to whether one "comes out" or not. One can make political assessments about each of these positions, which are quite valid (such as Cash posted above), but the real issue is how good is life going to be for the person making that decision. To say that one "must" do one or the other is simply disingenuous about consequences, both intended and unintended. Just because it turned out well for someone--of course one is delighted to hear that--does not mean it would be a good result for everyone without exception.
However, I think the socialization which one undergoes in the processes of life definitely make long-term, deep-seated attitudes about the willingness for one making the decision to choose to come out, and a large part of that is age-related/generational. Younger people have only emotionally known the years and the influences of the years in which they have lived, obviously. Thus, younger people have lived during a period of time where being labeled as homosexual is acceptable, much more than earlier and would not now be a death knell for important considerations (such as, for example, career choices, usually.) Thus, it seems today for younger people it makes much more sense to come out and live their lives however. For an older person, the decision has a lot more potential baggage with which to deal, which may or may not be a good idea for THAT person's emotional well-being. It really is an individual decision. Most importantly, there is no "obligation" that one should come out for the betterment of others. It is extremely good and nice if they do, but is is NOT an obligation so to do.
An example of this lack of obligation is the unfortunately-now-late Sally Ride. Her sexual orientation, were it known earlier, would have seriously impeded in those earlier years the effectiveness of her life's works and accomplishments, as the stupid media would have been continually harping on her homosexuality and options she enjoyed might well have been denied to her on that account, including possibly having been chosen as an astronaut.
