There is no correlation between the opinion one has of public affection and whether someone is in the closet. Straight folks, who have no closet issues, have various opinions on the matter. Some would approve and others would disapprove. It's personal taste.
And just because someone is in the closet doesn't mean they wouldn't engage in such behavior. Being in the closet is based on whether those who are closest to you know whether or not you're gay. Not the general public. Some closeted guys wouldn't mind making out in public as the OP did if they felt there would be no chance of getting caught by someone they know.
And if it matters to you, my private pics are my face pics. I was actually surprised when I first came to this site how many had face pics. Kudos to you guys. But on a message board, I just prefer to be judged by the content of my posts.
