I'm gonna say it here too. Allow me to be crystal fucking clear.
It is not cowardly to stay in the closet. Full stop. You do not owe anyone any part of yourself you aren't ready to share
If you unable to come out because you fear for your safety or well-being or because you know it will cause you substantial discomfort, that is not a defect in you. It's a failure of the society in which you live and the community surrounding you.
If you just don't want to share that part of yourself, that is valid and I support you
