I am slowly over time seeing you think about taking this step. Only you can decide this for yourself, and you shouldn't listen too much to any of the rest of us.
Your personal safety is priority number one. The very question you ask implies that this might be an issue for you. If so, don't do it, not where you are. Try to examine your circumstances rationally. Is your apprehension reasonable? If not, on to the next thing.
Your job/housing. Depending upon where you work (I don't know the status of antidiscrimination laws in NV), you may have "protected class" status and therefore cannot lose your job or home for being gay. If you don't have this protection, your personal relationship with your employer/supervisor is crucial to your decision. If you own your own home, the neighbors can't do much to you unless you are hosting some very loud orgies at all hours of the night. As far as any sort of harrassment, you have to be the judge as to the kind of people you live near. Again, is your apprehension really reasonable? If you are a tenant, the question again is the nature of your personal relationship with your landlord.
Your personal/family relationships. Are you prepared to lose people in your life that you may care deeply about, but as it turns out, don't actually love the real you anyway? Take the time to think carefully about each close relationship you may have. Are you overreacting to what might happen? Some people will surprise you, both in good and bad ways.
All of us here at RJ have been through this process at some point in our lives, and we have all survived it. I personally have lost my job (military, duh) because of it, but I knew that was ultimately in the cards for me anyway. My husband was bashed last year, but he was actually more angry than traumatized, and he's well over it now.
My last two cents. If the answers to most of the above questions leads to remain in the closet, consider whether all the subterfuge, as dramatic and spy-movie as it moght be, is worth staying in your present location.
Peace to you brutha...
