RightNYC needs to grace us with his knowledge.
Let me make it simple for you:
1) Being openly gay in the military is still against the rules.
2) Right now the military cannot punish someone for being openly gay.
The two are separate but related. The separation is important in understanding the nature of this ruling. It is still not really safe to be out of the closet for a couple of reasons. One is that #2 could be reversed, in which case if you come out now, you could be kicked out later. The other reason is that #1 still makes it unacceptable, even if you can't be punished for it.
I seriously doubt we are going to see gays coming out right now. The whole rule needs to be destroyed before that can safely happen.
