We won't- until we all can.
As a youth LGBT organization, we definitely get our share of questions about coming out. We realize that the decision to come out (or not) is highly individual and a number of factors (including family acceptance, economic resources, community support, etc) are involved. The common feature of all these decisions is that they require some degree of communication--someone to talk to, in other words. That "someone" can be online or in person or on the phone or in a book, but it always helps to build that support network. I've compiled some resources for youth (or anyone, really) to seek out when coming out. Remember it's not something you have to do, or something you have to do all at once. You also don't have to come out as the same thing all the time (you might refer to yourself as "trans" in one situation or "genderqueer" in another, for example). Again, the experience is individual. But you don't have to do it alone!
Reach out to your friends, family, community, schools, the online queer community--support is out there!
