I wouldn't want anyone 'forced' out, unless we are talking hypocritical, hatemonger politicians/preachers, as Veggie mentioned.
Until we live in a world where LGBT people feel free to express themselves with no fear and 'coming out' is no longer even an issue, then I have to respect personal choices. If kids can grow up knowing that their family and friends, as well as society, won't have a problem with their sexuality/gender identities, then so much heartache will be avoided. Unfortunately, this is still a long way off, even in this country.
Did anyone watch Long Lost Family, last night? A woman in her fifties was searching for her brother, who had told their parents that he was gay, when he was 21. He had been banished from the family and she, as a 14 year old, was told never to mention his name again. She didn't find out why, until her parents died. She thought he'd done something terrible, like murder. So, for 40 years, she had missed out on a relationship with her favourite brother, and he had had no relationship with his family, just because he was gay.
