Ehh. Well, unfortunately, politicians feel that it is necessary for them to stay closeted in order to be able to be elected. The reason they do this is because they feel that the people won't elect a gay man to office. And unfortunately, this almost always seems to be the case.
What needs to happen is that there needs to be more openly gay & lesbian public figures. Not just celebrities, but people in government as well. The more openly gay people there are in office, the more people will start accepting it. But, alas, that's a long time from coming.
We haven't even elected a woman or black president yet. Although, I'm betting that we'll have either one next year
