Purely hypothetical or a fantasy because I believe its not possible but a gut check question a lot of us ask ourselves. If you knew that if you came out to family, friends and co-workers and everyone ...and I mean everyone would positively accept it, would you come out publicly? For me the toughest would be my parents and friends. Co-workers and people I meet in the near future, not an issue. My answer (with anxiety) is, yes. Now let me ask part two of that question. After a week goes by and everyone turns to 'normal', that is they know you are gay and you are out but their real feelings and thoughts appear, would you still say yes or stay closeted? There's no amnesty after that but you know both questions ahead of time. My answer sadly at this time is, no. As a disclaimer: I am out to about 8 or 10 people but discreet.
I'd have to say yes both times. It would take such a great effort to do it the first time, why undo it? Especially when it's the coming out conversation that is the worst and that part would be done already and gone smoothly. I would go for it, yeah!
