This society puts so much pressure on people for being different. But then why do they say be your self, if who you really are isn't good enough for them. Coming out of the closet isn't that easy. It seems as if the closet would feel like a safer place to be, you alone accepting yourself. But if you accept yourself what does it matter what they think?
No matter what, you are a human being and you shouldn't hide from the world in a closet just because someone doesn't accept you. So really what " not coming out of the closet" means is the pressure that this society puts on someone will lead them to be something they aren't and make them hide their true emotions.
