If Being Gay Is Natural, Normal, And Acceptable, Why Do You Need To "Come Out"?

I have seen a rash of videos on the internet and celebrated in the media of people coming out of the closet to the their friends and family. They take a private matter of sexual orientation and broadcast it for the world to see. They are then interviewed by the media to celebrate their courage and bravery, encouraging others to film their coming out and posting it on the internet.

I can't help but wonder why they feel the need to "come out" in the first place, let alone record it and post it on the internet, if they are comfortable with their sexuality. You don't see straight people doing this, and your sexuality is generally considered something personal.

I am convinced that the individuals doing this are looking for both validation from others as well as attention. They are unsure of their sexuality and need confirmation from other people that it is okay. They also want to show the world they are gay to draw attention and praise to themselves to make them feel special. It is a private matter that should be discussed privately, not held up for the whole world to take notice. Doing something like this brings your credibility into question, because if you were secure in the sexuality, you wouldn't need validation from anyone.
