Coming out is often presumed to be some kind of once in a lifetime event. The reality for most LGBT people is that they have to come out again and again in life in situation after situation in which their identity is not the norm.
This includes coming out at school, college, to a doctor, to parents, to a spouse, from the pulpit, to a friend, to an enemy or rival, in a sports club, to a sibling and countless occasions when false assumptions have been made.
Many find the experience of coming out a liberating one in the end. However, it also has to be acknowledged that coming out can be a traumatic experience. No-one ever knows how another person will behave if one comes out to them. Sometimes people have lost their home, their children, their job as a result of coming out.
Ultimately, coming out is about living as a person of integrity and truth.
Sometimes LGBT people like to meet in LGBT spaces precisely because they want to meet in social spaces where coming out is completely unnecessary.
