Reading the responses here it seems that many are unwilling to come out because they fear risking ties with their families, friends, or in some cases risking even their lives. This has been my experience as well. I have lost a childhood friend as a result of me coming out to him. I can't handle losing my other friends and families too!
It has made me wonder: what do you value most in your life? Truth? Being who you are and cutting ties with those that don't accept you? Or keeping everyone in your life, lying about yourself and your identity, and enjoy the convenience of having an otherwise "normal" life?
