Scout, that is a very controversial issue. My own standard is that if a person occupies a public position, whether elected or otherwise, and is public on issues affecting equal rights, gay lifestyle, etc, they have made the question of their sexuality public.
I am not a fan of outing someone because their parent is famous or public on this issue, but certainly any politician who, as all those listed in the article, have made being gay a political issue, are fair game for "outing."
