Anytime an established actor comes out of the closet, he should be applauded. It's a brave thing to do in Hollywood. Not only is he confronting the prejudices of Middle America, but chances are he's also disappointing his resistant agent, facing the prejudices of homophobic producers and casting directors, and maybe even risking financial ruin. It takes guts.
That said, I reserve my biggest admiration for actors who were never in the closet to begin with. To me, those are the true heroes. As difficult as the acting profession is, starting out with no secrets is truly an act of courage.
