This is a very good point, one that I thought about noting in a response where I discussed my identities online, but chose not to. --Luckily I'm at a point in my life - both physically and mentally - where I don't have to hide who I am to others. So to that extent, I don't feel that I have to try to either hide or specifically state that I'm gay in any normal social interaction.
Unfortunately many people - even in the US - don't have this luxury. I saw the way the one person in my high school was brave enough to come out was ostracized, and given that I was already a target, I knew there was no way I could put up with what he had to go through. For Facebook to be working this hard to strip away the ability for people to have one image in public and another in private, well, it could end up hurting a lot of people.
