I almost never post here these days, but I'll unlurk for a moment.
What you have said, frankly, is nonsense. (And this is from a person who has had an active out-and-about life for six years.) Shoving and implicitly shaming people for not getting out the door is not constructive; some people indeed have valid reasons for staying in the closet. It's decidedly not your role to say otherwise.
The value of this forum, and it's a profound value, is that it allows the members to learn from the collective wisdom of our many experiences. You read about good outings, and bad. You maybe see a positive sign in your hometown, or a sad story about a similarly situated person who came to an awful situation. But the blessing of a forum like this one is that the participants can distill the collective experiences and learning of hundreds of others. And with that learning, people can make a much more informed decision about how best to live with the strange gender situation we have been given. Maybe they come to realize that they can in fact get out, and in that case YAY TEAM! I'll cheerlead with the best of them. Maybe they come to a more informed appreciation that they're best off remaining closeted. It may be a sad realization, but at least better than a decision made in comparative ignorance.
Against the benefit of learning from our accumulated wisdom, the presumptive values dictated by one person don't really stack up.
